 *
 * @example
 *
 * ```js
 * map.on('click', function(e) {

 *
 * map.on('click', onClick);
 * map.off('click', onClick);

/*
 * @class Control.Layers
 * @aka L.Control.Layers
 * @inherits Control
 *
 * The layers control gives users the ability to switch between different base layers and switch overlays on/off (check out the [detailed example](http://leafletjs.com/examples/layers-control/)). Extends `Control`.
 *
 * @example
 *
 * ```js
 * var baseLayers = {
 * 	"Mapbox": mapbox,
 * 	"OpenStreetMap": osm
 * };
 *
 * var overlays = {
 * 	"Marker": marker,
 * 	"Roads": roadsLayer
 * };
 *
 * L.control.layers(baseLayers, overlays).addTo(map);
 * ```
 *
 * The `baseLayers` and `overlays` parameters are object literals with layer names as keys and `Layer` objects as values:
 *
 * ```js
 * {
 *     "<someName1>": layer1,
 *     "<someName2>": layer2
 * }
 * ```
 *
 * The layer names can contain HTML, which allows you to add additional styling to the items:
 *
 * ```js
 * {"<img src='my-layer-icon' /> <span class='my-layer-item'>My Layer</span>": myLayer}
 * ```

 *
 * @method onAdd(map: Map): this
 * Should contain code that creates DOM elements for the layer, adds them to `map panes` where they should belong and puts listeners on relevant map events. Called on [`map.addLayer(layer)`](#map-addlayer).
 *
 * @method onRemove(map: Map): this
 * Should contain all clean up code that removes the layer's elements from the DOM and removes listeners previously added in [`onAdd`](#layer-onadd). Called on [`map.removeLayer(layer)`](#map-removelayer).
 *
 * @method getEvents(): Object
 * This optional method should return an object like `{ viewreset: this._reset }` for [`addEventListener`](#evented-addeventlistener). The event handlers in this object will be automatically added and removed from the map with your layer.
 *
 * @method getAttribution(): String
 * This optional method should return a string containing HTML to be shown on the `Attribution control` whenever the layer is visible.
 *
 * @method beforeAdd(map: Map): this
 * Optional method. Called on [`map.addLayer(layer)`](#map-addlayer), before the layer is added to the map, before events are initialized, without waiting until the map is in a usable state. Use for early initialization only.

 *
 * A class for drawing polygon overlays on a map. Extends `Polyline`.
 *
 * Note that points you pass when creating a polygon shouldn't have an additional last point equal to the first one — it's better to filter out such points.
 *
 *
 * @example
 *
 * ```js
 * // create a red polygon from an array of LatLng points
 * var latlngs = [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]];
 *
 * var polygon = L.polygon(latlngs, {color: 'red'}).addTo(map);
 *
 * // zoom the map to the polygon
 * map.fitBounds(polygon.getBounds());
 * ```
 *
 * You can also pass an array of arrays of latlngs, with the first array representing the outer shape and the other arrays representing holes in the outer shape:
 *
 * ```js
 * var latlngs = [
 *   [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring
 *   [[37.29, -108.58],[40.71, -108.58],[40.71, -102.50],[37.29, -102.50]] // hole
 * ];
 * ```
 *
 * Additionally, you can pass a multi-dimensional array to represent a MultiPolygon shape.
 *
 * ```js
 * var latlngs = [
 *   [ // first polygon
 *     [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring
 *     [[37.29, -108.58],[40.71, -108.58],[40.71, -102.50],[37.29, -102.50]] // hole

 *   Add a positive x offset to move the tooltip to the right, and a positive y offset to
 *   move it to the bottom. Negatives will move to the left and top.
 * - the `tooltipAnchor` Icon option: this will only be considered for Marker. You

/*
 * @class GridLayer
 * @inherits Layer
 * @aka L.GridLayer
 *
 * Generic class for handling a tiled grid of HTML elements. This is the base class for all tile layers and replaces `TileLayer.Canvas`.
 * GridLayer can be extended to create a tiled grid of HTML elements like `<canvas>`, `<img>` or `<div>`. GridLayer will handle creating and animating these DOM elements for you.
 *
 *
 * @section Synchronous usage
 * @example
 *
 * To create a custom layer, extend GridLayer and implement the `createTile()` method, which will be passed a `Point` object with the `x`, `y`, and `z` (zoom level) coordinates to draw your tile.
 *
 * ```js
 * var CanvasLayer = L.GridLayer.extend({
 *     createTile: function(coords){
 *         // create a <canvas> element for drawing
 *         var tile = L.DomUtil.create('canvas', 'leaflet-tile');
 *
 *         // setup tile width and height according to the options
 *         var size = this.getTileSize();
 *         tile.width = size.x;
 *         tile.height = size.y;
 *
 *         // get a canvas context and draw something on it using coords.x, coords.y and coords.z
 *         var ctx = tile.getContext('2d');
 *
 *         // return the tile so it can be rendered on screen
 *         return tile;
 *     }
 * });
 * ```
 *
 * @section Asynchronous usage
 * @example
 *
 * Tile creation can also be asynchronous, this is useful when using a third-party drawing library. Once the tile is finished drawing it can be passed to the `done()` callback.
 *
 * ```js
 * var CanvasLayer = L.GridLayer.extend({
 *     createTile: function(coords, done){
 *         var error;
 *
 *         // create a <canvas> element for drawing
 *         var tile = L.DomUtil.create('canvas', 'leaflet-tile');
 *
 *         // setup tile width and height according to the options
 *         var size = this.getTileSize();
 *         tile.width = size.x;
 *         tile.height = size.y;
 *
 *         // draw something asynchronously and pass the tile to the done() callback
 *         setTimeout(function() {
 *             done(error, tile);
 *         }, 1000);
 *
 *         return tile;
 *     }
 * });

 *
 * Allows vector layers to be displayed with [SVG](https://developer.mozilla.org/docs/Web/SVG).
 * Inherits `Renderer`.
 *
 * Due to [technical limitations](http://caniuse.com/#search=svg), SVG is not
 * available in all web browsers, notably Android 2.x and 3.x.
 *
 * Although SVG is not available on IE7 and IE8, these browsers support
 * [VML](https://en.wikipedia.org/wiki/Vector_Markup_Language)
 * (a now deprecated technology), and the SVG renderer will fall back to VML in
 * this case.
 *
 * @example
 *
 * Use SVG by default for all paths in the map:
 *
 * ```js
 * var map = L.map('map', {
 * 	renderer: L.svg()
 * });
 * ```
 *
 * Use a SVG renderer with extra padding for specific vector geometries:
 *
 * ```js
 * var map = L.map('map');
 * var myRenderer = L.svg({ padding: 0.5 });
 * var line = L.polyline( coordinates, { renderer: myRenderer } );
 * var circle = L.circle( center, { renderer: myRenderer } );
 * ```
