* @class Evented

*
* A set of methods shared between event-powered classes (like `Map` and `Marker`). Generally, events allow you to execute some function when something happens with an object (e.g. the user clicks on the map, causing the map to fire `'click'` event).
*
* @example
*
* ```js
* map.on('click', function(e) {
* alert(e.latlng);
* } );
* ```
*
* Leaflet deals with event listeners by reference, so if you want to add a listener and then remove it, define it as a function:
*
* ```js
* function onClick(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}
* ```

*
* 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 = [

/*
* @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

* Allows vector layers to be displayed with [SVG](https://developer.mozilla.org/docs/Web/SVG).

* Due to [technical limitations](http://caniuse.com/#search=svg), SVG is not

* Although SVG is not available on IE7 and IE8, these browsers support

* 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 } );
