/**
 * The Spine loader is used to load in JSON spine data
 * To generate the data you need to use http://esotericsoftware.com/ and export in the "JSON" format
 * Due to a clash of names  You will need to change the extension of the spine file from *.json to *.anim for it to load
 * See example 12 (http://www.goodboydigital.com/pixijs/examples/12/) to see a working example and check out the source
 * You will need to generate a sprite sheet to accompany the spine data
 * When loaded this class will dispatch a "loaded" event
 *
 * @class SpineLoader
 * @uses EventTarget
 * @constructor
 * @param url {String} The url of the JSON file
 * @param crossorigin {Boolean} Whether requests should be treated as crossorigin
