 * @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 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;
 *     }
 * });
 * ```
