    https://www.npmjs.com/package/generate-license-file

    The following npm package may be included in this product:

     - @fortawesome/fontawesome-free@5.12.1

    This package contains the following license and notice below:

    Font Awesome Free License
    -------------------------

    Font Awesome Free is free, open source, and GPL friendly. You can use it for
    commercial projects, open source projects, or really almost whatever you want.
    Full Font Awesome Free license: https://fontawesome.com/license/free.

    # Icons: CC BY 4.0 License (https://creativecommons.org/licenses/by/4.0/)
    In the Font Awesome Free download, the CC BY 4.0 license applies to all icons
    packaged as SVG and JS file types.

    # Fonts: SIL OFL 1.1 License (https://scripts.sil.org/OFL)
    In the Font Awesome Free download, the SIL OFL license applies to all icons
    packaged as web and desktop font files.

    # Code: MIT License (https://opensource.org/licenses/MIT)

    non-icon files.

    # Attribution
    Attribution is required by MIT, SIL OFL, and CC BY licenses. Downloaded Font
    Awesome Free files already contain embedded comments with sufficient
    attribution, so you shouldn't need to do anything additional when using these
    files normally.

    We've kept attribution comments terse, so we ask that you do not actively work
    to remove them from files, especially code. They're a great way for folks to
    learn about Font Awesome.

    All brand icons are trademarks of their respective owners. The use of these
    trademarks does not indicate endorsement of the trademark holder by Font
    Awesome, nor vice versa. **Please do not use brand logos for any purpose except

    Introduction
    ----
    **JsBarcode** is a **barcode generator** written in JavaScript. It supports multiple barcode formats and works in browsers and with *Node.js*. It has *no dependencies* when it is used for the web but works with *jQuery* if you are into that.

    Demo
    ----
    #### [Barcode Generator](http://lindell.github.io/JsBarcode/generator/)
    #### [Simple CodePen Demo](http://codepen.io/lindell/pen/eZKBdO?editors=1010)
    #### [Settings CodePen Demo](http://codepen.io/lindell/pen/mPvLXx?editors=1010)

    Supported barcodes:
    ----
    * [CODE128](https://github.com/lindell/JsBarcode/wiki/CODE128)
      * CODE128 (automatic mode switching)
      * CODE128 A/B/C (force mode)
    * [EAN](https://github.com/lindell/JsBarcode/wiki/EAN)

    * [Codabar](https://github.com/lindell/JsBarcode/wiki/codabar)

    Examples for browsers:
    ----

    #### First create a canvas (or image)
    ````html

    ````

    #### Simple example:
    ````javascript
    JsBarcode("#barcode", "Hi!");
    // or with jQuery
    $("#barcode").JsBarcode("Hi!");
    ````

    ##### Result:
    ![Result](https://s3-eu-west-1.amazonaws.com/js-barcode/barcodes/simple.svg)

    #### Example with options:
    ````javascript
    JsBarcode("#barcode", "1234", {
      format: "pharmacode",
      lineColor: "#0aa",
      width:4,
      height:40,
      displayValue: false
    });
    ````
    ##### Result:
    ![Result](https://s3-eu-west-1.amazonaws.com/js-barcode/barcodes/advanced.svg)

    #### More advanced use case:
    ````javascript
    JsBarcode("#barcode")
      .options({font: "OCR-B"}) // Will affect all barcodes
      .EAN13("1234567890128", {fontSize: 18, textMargin: 0})
      .blank(20) // Create space between the barcodes
      .EAN5("12345", {height: 85, textPosition: "top", fontSize: 16, marginTop: 15})
      .render();
    ````
    ##### Result:
    ![Result](https://s3-eu-west-1.amazonaws.com/js-barcode/barcodes/simple.svg)

    #### Or define the value and options in the HTML element:
    Use any `jsbarcode-*` or `data-*` as attributes where `*` is any option.
    ````html

    ````

    And then initialize it with:
    ````javascript
    JsBarcode(".barcode").init();
    ````

    ##### Result:
    ![Result](https://s3-eu-west-1.amazonaws.com/js-barcode/barcodes/init.svg)

    #### Retrieve the barcode values so you can render it any way you'd like
    Pass in an object which will be filled with data.
    ```javascript
    const data = {};
    JsBarcode(data, 'text', {...options});
    ```
    data will be filled with a ``` encodings ``` property which has all the needed values.
    See wiki for an example of what data looks like.

    Setup for browsers:
    ----
    ### Step 1:
    Download or get the CDN link to the script:

    | Name | Supported barcodes | Size (gzip) | CDN / Download |
    |------|--------------------|:-----------:|---------------:|
    |  *All*  |  *All the barcodes!*  |  *10.1 kB*  |  *[JsBarcode.all.min.js][1]*  |
    |  CODE128  |  CODE128 (auto and force mode)  |  6.2 kB  |  [JsBarcode.code128.min.js][2]  |
    |  CODE39  |  CODE39  |  5.1 kB  |  [JsBarcode.code39.min.js][3]  |
    |  EAN / UPC  |  EAN-13, EAN-8, EAN-5, EAN-2, UPC (A)  |  6.7 kB  |  [JsBarcode.ean-upc.min.js][4]  |
    |  ITF  |  ITF, ITF-14  |  5 kB  |  [JsBarcode.itf.min.js][5]  |
    |  MSI  |  MSI, MSI10, MSI11, MSI1010, MSI1110  |  5 kB  |  [JsBarcode.msi.min.js][6]  |
    |  Pharmacode  |  Pharmacode  |  4.7 kB  |  [JsBarcode.pharmacode.min.js][7]  |
    |  Codabar  |  Codabar  |  4.9 kB  |  [JsBarcode.codabar.min.js][8]  |

    ### Step 2:
    Include the script in your code:

    ````html

    ````

    ### Step 3:
    You are done! Go generate some barcodes :smile:

    Bower and npm:
    ----
    You can also use [Bower](http://bower.io) or [npm](https://www.npmjs.com) to install and manage the library.
    ````bash
    bower install jsbarcode --save
    ````
    ````bash
    npm install jsbarcode --save
    ````

    Node.js:
    ----

    #### With canvas:
    ```` javascript
    var JsBarcode = require('jsbarcode');

    // Canvas v1
    var Canvas = require("canvas");
    // Canvas v2
    var { createCanvas } = require("canvas");

    // Canvas v1
    var canvas = new Canvas();
    // Canvas v2
    var canvas = createCanvas();

    JsBarcode(canvas, "Hello");

    // Do what you want with the canvas
    // See https://github.com/Automattic/node-canvas for more information
    ````

    #### With svg:
    ```` javascript
    const { DOMImplementation, XMLSerializer } = require('xmldom');
    const xmlSerializer = new XMLSerializer();
    const document = new DOMImplementation().createDocument('http://www.w3.org/1999/xhtml', 'html', null);
    const svgNode = document.createElementNS('http://www.w3.org/2000/svg', 'svg');

    JsBarcode(svgNode, 'test', {
        xmlDocument: document,
    });

    const svgText = xmlSerializer.serializeToString(svgNode);
    ````

    ## Using the plugin
    Include the plugin CSS and JS files on your page after Leaflet files, using your method of choice:
    * [Download the `v1.4.1` release](https://github.com/Leaflet/Leaflet.markercluster/archive/v1.4.1.zip)
    * Use unpkg CDN: `https://unpkg.com/leaflet.markercluster@1.4.1/dist/`
    * Install with npm: `npm install leaflet.markercluster`

    In each case, use files in the `dist` folder:
    * `MarkerCluster.css`
    * `MarkerCluster.Default.css` (not needed if you use your own `iconCreateFunction` instead of the default one)
    * `leaflet.markercluster.js` (or `leaflet.markercluster-src.js` for the non-minified version)

    ### Building, testing and linting scripts
    Install jake `npm install -g jake` then run `npm install`
    * To check the code for errors and build Leaflet from source, run `jake`.
    * To run the tests, run `jake test`.

    ### Examples
    See the included examples for usage.

    The [realworld example](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-realworld.388.html) is a good place to start, it uses all of the defaults of the clusterer.
    Or check out the [custom example](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-custom.html) for how to customise the behaviour and appearance of the clusterer

    ### Usage
    Create a new MarkerClusterGroup, add your markers to it, then add it to the map

    ```javascript
    var markers = L.markerClusterGroup();
    markers.addLayer(L.marker(getRandomLatLng(map)));
    ... Add more layers ...
    map.addLayer(markers);
    ```

    ## Options
    ### Defaults
    By default the Clusterer enables some nice defaults for you:
    * **showCoverageOnHover**: When you mouse over a cluster it shows the bounds of its markers.
    * **zoomToBoundsOnClick**: When you click a cluster we zoom to its bounds.
    * **spiderfyOnMaxZoom**: When you click a cluster at the bottom zoom level we spiderfy it so you can see all of its markers. (*Note: the spiderfy occurs at the current zoom level if all items within the cluster are still clustered at the maximum zoom level or at zoom specified by `disableClusteringAtZoom` option*)
    * **removeOutsideVisibleBounds**: Clusters and markers too far from the viewport are removed from the map for performance.
    * **spiderLegPolylineOptions**: Allows you to specify [PolylineOptions](http://leafletjs.com/reference.html#polyline-options) to style spider legs. By default, they are `{ weight: 1.5, color: '#222', opacity: 0.5 }`.

    You can disable any of these as you want in the options when you create the MarkerClusterGroup:
    ```javascript
    var markers = L.markerClusterGroup({
    	spiderfyOnMaxZoom: false,
    	showCoverageOnHover: false,
    	zoomToBoundsOnClick: false
    });
    ```

    ### Customising the Clustered Markers
    As an option to MarkerClusterGroup you can provide your own function for creating the Icon for the clustered markers.
    The default implementation changes color at bounds of 10 and 100, but more advanced uses may require customising this.
    You do not need to include the .Default css if you go this way.
    You are passed a MarkerCluster object, you'll probably want to use `getChildCount()` or `getAllChildMarkers()` to work out the icon to show.

    ```javascript
    var markers = L.markerClusterGroup({
    	iconCreateFunction: function(cluster) {
    		return L.divIcon({ html: '' + cluster.getChildCount() + '' });
    	}
    });
    ```

    Check out the [custom example](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-custom.html) for an example of this.

    If you need to update the clusters icon (e.g. they are based on markers real-time data), use the method [refreshClusters()](#refreshing-the-clusters-icon).

    ### Customising Spiderfy shape positions
    You can also provide a custom function as an option to MarkerClusterGroup to override the spiderfy shape positions. The example below implements linear spiderfy positions which overrides the default circular shape.

    ```javascript
    var markers = L.markerClusterGroup({
    	spiderfyShapePositions: function(count, centerPt) {
                    var distanceFromCenter = 35,
                        markerDistance = 45,
                        lineLength = markerDistance * (count - 1),
                        lineStart = centerPt.y - lineLength / 2,
                        res = [],
                        i;

                    res.length = count;

                    for (i = count - 1; i >= 0; i--) {
                        res[i] = new Point(centerPt.x + distanceFromCenter, lineStart + markerDistance * i);
                    }

                    return res;
                }
    });
    ```

    ### All Options
    #### Enabled by default (boolean options)
    * **showCoverageOnHover**: When you mouse over a cluster it shows the bounds of its markers.
    * **zoomToBoundsOnClick**: When you click a cluster we zoom to its bounds.
    * **spiderfyOnMaxZoom**: When you click a cluster at the bottom zoom level we spiderfy it so you can see all of its markers. (*Note: the spiderfy occurs at the current zoom level if all items within the cluster are still clustered at the maximum zoom level or at zoom specified by `disableClusteringAtZoom` option*).
    * **removeOutsideVisibleBounds**: Clusters and markers too far from the viewport are removed from the map for performance.
    * **animate**: Smoothly split / merge cluster children when zooming and spiderfying. If `L.DomUtil.TRANSITION` is false, this option has no effect (no animation is possible).

    #### Other options
    * **animateAddingMarkers**: If set to true (and `animate` option is also true) then adding individual markers to the MarkerClusterGroup after it has been added to the map will add the marker and animate it into the cluster. Defaults to false as this gives better performance when bulk adding markers. addLayers does not support this, only addLayer with individual Markers.
    * **disableClusteringAtZoom**: If set, at this zoom level and below, markers will not be clustered. This defaults to disabled. [See Example](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-realworld-maxzoom.388.html). Note: you may be interested in disabling `spiderfyOnMaxZoom` option when using `disableClusteringAtZoom`.
    * **maxClusterRadius**: The maximum radius that a cluster will cover from the central marker (in pixels). Default 80. Decreasing will make more, smaller clusters. You can also use a function that accepts the current map zoom and returns the maximum cluster radius in pixels.
    * **polygonOptions**: Options to pass when creating the L.Polygon(points, options) to show the bounds of a cluster. Defaults to empty, which lets Leaflet use the [default Path options](http://leafletjs.com/reference.html#path-options).
    * **singleMarkerMode**: If set to true, overrides the icon for all added markers to make them appear as a 1 size cluster. Note: the markers are not replaced by cluster objects, only their icon is replaced. Hence they still react to normal events, and option `disableClusteringAtZoom` does not restore their previous icon (see [#391](https://github.com/Leaflet/Leaflet.markercluster/issues/391)).
    * **spiderLegPolylineOptions**: Allows you to specify [PolylineOptions](http://leafletjs.com/reference.html#polyline-options) to style spider legs. By default, they are `{ weight: 1.5, color: '#222', opacity: 0.5 }`.
    * **spiderfyDistanceMultiplier**: Increase from 1 to increase the distance away from the center that spiderfied markers are placed. Use if you are using big marker icons (Default: 1).
    * **iconCreateFunction**: Function used to create the cluster icon. See [the default implementation](https://github.com/Leaflet/Leaflet.markercluster/blob/15ed12654acdc54a4521789c498e4603fe4bf781/src/MarkerClusterGroup.js#L542) or the [custom example](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-custom.html).
    * **spiderfyShapePositions**: Function used to override spiderfy default shape positions.
    * **clusterPane**: Map pane where the cluster icons will be added. Defaults to L.Marker's default (currently 'markerPane'). [See the pane example](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-pane.html).

    #### Chunked addLayers options
    Options for the [addLayers](#bulk-adding-and-removing-markers) method. See [#357](https://github.com/Leaflet/Leaflet.markercluster/issues/357) for explanation on how the chunking works.
    * **chunkedLoading**: Boolean to split the addLayer**s** processing in to small intervals so that the page does not freeze.
    * **chunkInterval**: Time interval (in ms) during which addLayers works before pausing to let the rest of the page process. In particular, this prevents the page from freezing while adding a lot of markers. Defaults to 200ms.
    * **chunkDelay**: Time delay (in ms) between consecutive periods of processing for addLayers. Default to 50ms.
    * **chunkProgress**: Callback function that is called at the end of each chunkInterval. Typically used to implement a progress indicator, e.g. [code in RealWorld 50k](https://github.com/Leaflet/Leaflet.markercluster/blob/master/example/marker-clustering-realworld.50000.html#L33-L49). Defaults to null. Arguments:
      1. Number of processed markers
      2. Total number of markers being added
      3. Elapsed time (in ms)

    ## Events
    Leaflet events like `click`, `mouseover`, etc. are just related to _Markers_ in the cluster.
    To receive events for clusters, listen to `'cluster' + '<eventName>'`, ex: `clusterclick`, `clustermouseover`, `clustermouseout`.

    Set your callback up as follows to handle both cases:

    ```javascript
    markers.on('click', function (a) {
    	console.log('marker ' + a.layer);
    });

    markers.on('clusterclick', function (a) {
    	// a.layer is actually a cluster
    	console.log('cluster ' + a.layer.getAllChildMarkers().length);
    });
    ```

    ### Additional MarkerClusterGroup Events

    - **animationend**: Fires when marker clustering/unclustering animation has completed
    - **spiderfied**: Fires when overlapping markers get spiderified (Contains ```cluster``` and ```markers``` attributes)
    - **unspiderfied**: Fires when overlapping markers get unspiderified (Contains ```cluster``` and ```markers``` attributes)

    ## Methods

    ### Group methods

    #### Adding and removing Markers
    `addLayer`, `removeLayer` and `clearLayers` are supported and they should work for most uses.

    #### Bulk adding and removing Markers
    `addLayers` and `removeLayers` are bulk methods for adding and removing markers and should be favoured over the single versions when doing bulk addition/removal of markers. Each takes an array of markers. You can use [dedicated options](#chunked-addlayers-options) to fine-tune the behaviour of `addLayers`.

    These methods extract non-group layer children from Layer Group types, even deeply nested. _However_, be noted that:
    - `chunkProgress` jumps backward when `addLayers` finds a group (since appending its children to the input array makes the total increase).
    - Groups are not actually added into the MarkerClusterGroup, only their non-group child layers. Therfore, `hasLayer` method will return `true` for non-group child layers, but `false` on any (possibly parent) Layer Group types.

    If you are removing a lot of markers it will almost definitely be better to call `clearLayers` then call `addLayers` to add the markers you don't want to remove back in. See [#59](https://github.com/Leaflet/Leaflet.markercluster/issues/59#issuecomment-9320628) for details.

    #### Getting the visible parent of a marker
    If you have a marker in your MarkerClusterGroup and you want to get the visible parent of it (Either itself or a cluster it is contained in that is currently visible on the map).
    This will return null if the marker and its parent clusters are not visible currently (they are not near the visible viewpoint)
    ```javascript
    var visibleOne = markerClusterGroup.getVisibleParent(myMarker);
    console.log(visibleOne.getLatLng());
    ```

    #### Refreshing the clusters icon
    If you have [customized](#customising-the-clustered-markers) the clusters icon to use some data from the contained markers, and later that data changes, use this method to force a refresh of the cluster icons.
    You can use the method:
    - without arguments to force all cluster icons in the Marker Cluster Group to be re-drawn.
    - with an array or a mapping of markers to force only their parent clusters to be re-drawn.
    - with an L.LayerGroup. The method will look for all markers in it. Make sure it contains only markers which are also within this Marker Cluster Group.
    - with a single marker.
    ```javascript
    markers.refreshClusters();
    markers.refreshClusters([myMarker0, myMarker33]);
    markers.refreshClusters({id_0: myMarker0, id_any: myMarker33});
    markers.refreshClusters(myLayerGroup);
    markers.refreshClusters(myMarker);
    ```

    The plugin also adds a method on L.Marker to easily update the underlying icon options and refresh the icon.
    If passing a second argument that evaluates to `true`, the method will also trigger a `refreshCluster` on the parent MarkerClusterGroup for that single marker.
    ```javascript
    // Use as many times as required to update markers,
    // then call refreshClusters once finished.
    for (i in markersSubArray) {
    	markersSubArray[i].refreshIconOptions(newOptionsMappingArray[i]);
    }
    markers.refreshClusters(markersSubArray);

    // If updating only one marker, pass true to
    // refresh this marker's parent clusters right away.
    myMarker.refreshIconOptions(optionsMap, true);
    ```

    #### Other Group Methods
    * **hasLayer**(layer): Returns true if the given layer (marker) is in the MarkerClusterGroup.
    * **zoomToShowLayer**(layer, callback): Zooms to show the given marker (spiderfying if required), calls the callback when the marker is visible on the map.

    ### Clusters methods
    The following methods can be used with clusters (not the group). They are typically used for event handling.

    #### Getting the bounds of a cluster
    When you receive an event from a cluster you can query it for the bounds.
    ```javascript
    markers.on('clusterclick', function (a) {
    	var latLngBounds = a.layer.getBounds();
    });
    ```

    You can also query for the bounding convex polygon.
    See [example/marker-clustering-convexhull.html](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-convexhull.html) for a working example.
    ```javascript
    markers.on('clusterclick', function (a) {
    	map.addLayer(L.polygon(a.layer.getConvexHull()));
    });
    ```

    #### Zooming to the bounds of a cluster
    When you receive an event from a cluster you can zoom to its bounds in one easy step.
    If all of the markers will appear at a higher zoom level, that zoom level is zoomed to instead.
    `zoomToBounds` takes an optional argument to pass [options to the resulting `fitBounds` call](http://leafletjs.com/reference.html#map-fitboundsoptions).

    See [marker-clustering-zoomtobounds.html](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-zoomtobounds.html) for a working example.
    ```javascript
    markers.on('clusterclick', function (a) {
    	a.layer.zoomToBounds({padding: [20, 20]});
    });
    ```

    #### Other clusters methods
    * **getChildCount**: Returns the total number of markers contained within that cluster.
    * **getAllChildMarkers(storage: array | undefined, ignoreDraggedMarker: boolean | undefined)**: Returns an array of all markers contained within this cluster (storage will be used if provided). If ignoreDraggedMarker is true and there is currently a marker dragged, the dragged marker will not be included in the array.
    * **spiderfy**: Spiderfies the child markers of this cluster
    * **unspiderfy**: Unspiderfies a cluster (opposite of spiderfy)

    ## Handling LOTS of markers
    The Clusterer can handle 10,000 or even 50,000 markers (in chrome). IE9 has some issues with 50,000.
    - [realworld 10,000 example](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-realworld.10000.html)
    - [realworld 50,000 example](https://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-realworld.50000.html)

    Note: these two examples use the `chunkedLoading` option set to true in order to avoid locking the browser for a long time.

    ## Sub-plugins
    Leaflet.markercluster plugin is very popular and as such it generates high and
    diverse expectations for increased functionalities.

    If you are in that case, be sure to have a look first at the repository
    [issues](https://github.com/Leaflet/Leaflet.markercluster/issues) in case what
    you are looking for would already be discussed, and some workarounds would be proposed.

    Check also the below sub-plugins:

    | Plugin | Description | Maintainer |
    | :----- | :---------- | :--------- |
    | [Leaflet.FeatureGroup.SubGroup](https://github.com/ghybs/Leaflet.FeatureGroup.SubGroup) | Creates a Feature Group that adds its child layers into a parent group when added to a map (e.g. through L.Control.Layers). Typical usage is to dynamically add/remove groups of markers from Marker Cluster. | [ghybs](https://github.com/ghybs) |
    | [Leaflet.MarkerCluster.LayerSupport](https://github.com/ghybs/Leaflet.MarkerCluster.LayerSupport) | Brings compatibility with L.Control.Layers and other Leaflet plugins. I.e. everything that uses direct calls to map.addLayer and map.removeLayer. | [ghybs](https://github.com/ghybs) |
    | [Leaflet.MarkerCluster.Freezable](https://github.com/ghybs/Leaflet.MarkerCluster.Freezable) | Adds the ability to freeze clusters at a specified zoom. E.g. freezing at maxZoom + 1 makes as if clustering was programmatically disabled. | [ghybs](https://github.com/ghybs) |
    | [Leaflet.MarkerCluster.PlacementStrategies](https://github.com/adammertel/Leaflet.MarkerCluster.PlacementStrategies) | Implements new strategies to position clustered markers (eg: clock, concentric circles, ...). Recommended to use with circleMarkers. [Demo](https://adammertel.github.io/Leaflet.MarkerCluster.PlacementStrategies/demo/demo1.html) | [adammertel](https://github.com/adammertel) / [UNIVIE](http://carto.univie.ac.at/) |
    | [Leaflet.MarkerCluster.List](https://github.com/adammertel/Leaflet.MarkerCluster.List) | Displays child elements in a list. Suitable for mobile devices. [Demo](https://adammertel.github.io/Leaflet.MarkerCluster.List/demo/demo1.html) | [adammertel](https://github.com/adammertel) / [UNIVIE](http://carto.univie.ac.at/) |

    Apache License
                               Version 2.0, January 2004

       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

       1. Definitions.

          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.

          "Licensor" shall mean the copyright owner or entity authorized by
          the copyright owner that is granting the License.

          "Legal Entity" shall mean the union of the acting entity and all
          other entities that control, are controlled by, or are under common
          control with that entity. For the purposes of this definition,
          "control" means (i) the power, direct or indirect, to cause the
          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the
          outstanding shares, or (iii) beneficial ownership of such entity.

          "You" (or "Your") shall mean an individual or Legal Entity
          exercising permissions granted by this License.

          "Source" form shall mean the preferred form for making modifications,
          including but not limited to software source code, documentation
          source, and configuration files.

          "Object" form shall mean any form resulting from mechanical
          transformation or translation of a Source form, including but
          not limited to compiled object code, generated documentation,
          and conversions to other media types.

          "Work" shall mean the work of authorship, whether in Source or
          Object form, made available under the License, as indicated by a
          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).

          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.

          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions
          to that Work or Derivative Works thereof, that is intentionally
          submitted to Licensor for inclusion in the Work by the copyright owner
          or by an individual or Legal Entity authorized to submit on behalf of
          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,
          and issue tracking systems that are managed by, or on behalf of, the
          Licensor for the purpose of discussing and improving the Work, but
          excluding communication that is conspicuously marked or otherwise
          designated in writing by the copyright owner as "Not a Contribution."

          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.

       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.

       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.

       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:

          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and

          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and

          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and

          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.

          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.

       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.

       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.

       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.

       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.

       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.

       END OF TERMS AND CONDITIONS

       APPENDIX: How to apply the Apache License to your work.

          To apply the Apache License to your work, attach the following
          boilerplate notice, with the fields enclosed by brackets "[]"
          replaced with your own identifying information. (Don't include
          the brackets!)  The text should be enclosed in the appropriate
          comment syntax for the file format. We also recommend that a
          file or class name and description of purpose be included on the
          same "printed page" as the copyright notice for easier
          identification within third-party archives.

    The following npm package may be included in this product:

     - murmurhash-js@1.0.0

    This package contains the following license and notice below:

    # MurmurHash.js

    An optimized JavaScript implementation of the MurmurHash algorithms.

    These algorithms take a JavaScript string (and a seed), and quickly create a non-cryptographic 32-bit hash from it. And by quick I mean sub-millisecond performance.

    More information about these algorithms can be found at:

    *	[MurmurHash Homepage](http://sites.google.com/site/murmurhash/)
    *	[Wikipedia Entry on MurmurHash](http://en.wikipedia.org/wiki/MurmurHash)

    ## Install

        npm install murmurhash-js

    ## API

    ```javascript
    var murmur = require("murmurhash-js")
    ```

    ### Methods

    #### `murmur.murmur2(key, seed)`
    Runs the murmur2 hash algorithm on the string `key` with initial seed `seed`.

    #### `murmur.murmur3(key, seed)`
    Runs the murmur3 hash algorithm on the string `key` with initial seed `seed`.

    **Note** `require("murmur-hash")` is the same as `murmur.murmur3`

       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

       1. Definitions.

          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.

          "Licensor" shall mean the copyright owner or entity authorized by
          the copyright owner that is granting the License.

          "Legal Entity" shall mean the union of the acting entity and all
          other entities that control, are controlled by, or are under common
          control with that entity. For the purposes of this definition,
          "control" means (i) the power, direct or indirect, to cause the
          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the
          outstanding shares, or (iii) beneficial ownership of such entity.

          "You" (or "Your") shall mean an individual or Legal Entity
          exercising permissions granted by this License.

          "Source" form shall mean the preferred form for making modifications,
          including but not limited to software source code, documentation
          source, and configuration files.

          "Object" form shall mean any form resulting from mechanical
          transformation or translation of a Source form, including but
          not limited to compiled object code, generated documentation,
          and conversions to other media types.

          "Work" shall mean the work of authorship, whether in Source or
          Object form, made available under the License, as indicated by a
          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).

          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.

          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions
          to that Work or Derivative Works thereof, that is intentionally
          submitted to Licensor for inclusion in the Work by the copyright owner
          or by an individual or Legal Entity authorized to submit on behalf of
          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,
          and issue tracking systems that are managed by, or on behalf of, the
          Licensor for the purpose of discussing and improving the Work, but
          excluding communication that is conspicuously marked or otherwise
          designated in writing by the copyright owner as "Not a Contribution."

          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.

       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.

       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.

       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:

          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and

          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and

          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and

          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.

          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.

       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.

       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.

       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.

       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.

       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.

       END OF TERMS AND CONDITIONS

       APPENDIX: How to apply the Apache License to your work.

          To apply the Apache License to your work, attach the following

          comment syntax for the file format. We also recommend that a
          file or class name and description of purpose be included on the
          same "printed page" as the copyright notice for easier
          identification within third-party archives.
