* A Class that loads a bunch of images &#x2F; sprite sheet files. Once the assets have been loaded they are added to the PIXI Texture cache and can be accessed easily through PIXI.Texture.fromFrameId(), PIXI.Texture.fromImage() and PIXI.Sprite.fromImage(), PIXI.Sprite.fromFromeId()
* When all items have been loaded this class will dispatch a &#x27;loaded&#x27; event
* As each individual item is loaded this class will dispatch a &#x27;progress&#x27; event
* @class AssetLoader
* @constructor
* @extends EventTarget
* @param assetURLs {Array} an array of image&#x2F;sprite sheet urls that you would like loaded supported. Supported image formats include &quot;jpeg&quot;, &quot;jpg&quot;, &quot;png&quot;, &quot;gif&quot;. Supported sprite sheet data formats only include &quot;JSON&quot; at this time
