	/**
	 * EventDispatcher provides methods for managing queues of event listeners and dispatching events.
	 *
	 * You can either extend EventDispatcher or mix its methods into an existing prototype or instance by using the
	 * EventDispatcher {{#crossLink "EventDispatcher/initialize"}}{{/crossLink}} method.
	 * 
	 * Together with the CreateJS Event class, EventDispatcher provides an extended event model that is based on the
	 * DOM Level 2 event model, including addEventListener, removeEventListener, and dispatchEvent. It supports
	 * bubbling / capture, preventDefault, stopPropagation, stopImmediatePropagation, and handleEvent.
	 * 
	 * EventDispatcher also exposes a {{#crossLink "EventDispatcher/on"}}{{/crossLink}} method, which makes it easier
	 * to create scoped listeners, listeners that only run once, and listeners with associated arbitrary data. The 
	 * {{#crossLink "EventDispatcher/off"}}{{/crossLink}} method is merely an alias to
	 * {{#crossLink "EventDispatcher/removeEventListener"}}{{/crossLink}}.
	 * 
	 * Another addition to the DOM Level 2 model is the {{#crossLink "EventDispatcher/removeAllEventListeners"}}{{/crossLink}}
	 * method, which can be used to listeners for all events, or listeners for a specific event. The Event object also 
	 * includes a {{#crossLink "Event/remove"}}{{/crossLink}} method which removes the active listener.
	 *
	 * <h4>Example</h4>
	 * Add EventDispatcher capabilities to the "MyClass" class.
	 *
	 *      EventDispatcher.initialize(MyClass.prototype);
	 *
	 * Add an event (see {{#crossLink "EventDispatcher/addEventListener"}}{{/crossLink}}).
	 *
	 *      instance.addEventListener("eventName", handlerMethod);
	 *      function handlerMethod(event) {
	 *          console.log(event.target + " Was Clicked");
	 *      }
	 *
	 * <b>Maintaining proper scope</b><br />
	 * Scope (ie. "this") can be be a challenge with events. Using the {{#crossLink "EventDispatcher/on"}}{{/crossLink}}
	 * method to subscribe to events simplifies this.
	 *
	 *      instance.addEventListener("click", function(event) {
	 *          console.log(instance == this); // false, scope is ambiguous.
	 *      });
	 *      
	 *      instance.on("click", function(event) {
	 *          console.log(instance == this); // true, "on" uses dispatcher scope by default.
	 *      });
	 * 
	 * If you want to use addEventListener instead, you may want to use function.bind() or a similar proxy to manage
	 * scope.
	 *
	 * <b>Browser support</b>
	 * The event model in CreateJS can be used separately from the suite in any project, however the inheritance model
	 * requires modern browsers (IE9+).

//  NOTE this is "Class" is purely to document audioSprite Setup and usage.


/**
 * <strong>Note: AudioSprite is not a class, but its usage is easily lost in the documentation, so it has been called
 * out here for quick reference.</strong>
 *
 * Audio sprites are much like CSS sprites or image sprite sheets: multiple audio assets grouped into a single file.
 * Audio sprites work around limitations in certain browsers, where only a single sound can be loaded and played at a
 * time. We recommend at least 300ms of silence between audio clips to deal with HTML audio tag inaccuracy, and to prevent
 * accidentally playing bits of the neighbouring clips.
 *
 * <strong>Benefits of Audio Sprites:</strong>
 * <ul>
 *     <li>More robust support for older browsers and devices that only allow a single audio instance, such as iOS 5.</li>
 *     <li>They provide a work around for the Internet Explorer 9 audio tag limit, which restricts how many different
 *     sounds that could be loaded at once.</li>
 *     <li>Faster loading by only requiring a single network request for several sounds, especially on mobile devices
 * where the network round trip for each file can add significant latency.</li>
 * </ul>
 *
 * <strong>Drawbacks of Audio Sprites</strong>
 * <ul>
 *     <li>No guarantee of smooth looping when using HTML or Flash audio. If you have a track that needs to loop
 * 		smoothly and you are supporting non-web audio browsers, do not use audio sprites for that sound if you can avoid
 * 		it.</li>
 *     <li>No guarantee that HTML audio will play back immediately, especially the first time. In some browsers
 *     (Chrome!), HTML audio will only load enough to play through at the current download speed – so we rely on the
 *     `canplaythrough` event to determine if the audio is loaded. Since audio sprites must jump ahead to play specific
 *     sounds, the audio may not yet have downloaded fully.</li>
 *     <li>Audio sprites share the same core source, so if you have a sprite with 5 sounds and are limited to 2
 * 		concurrently playing instances, you can only play 2 of the sounds at the same time.</li>
 * </ul>
 *
 * <h4>Example</h4>
 *
 *		createjs.Sound.initializeDefaultPlugins();
 *		var assetsPath = "./assets/";
 *		var sounds = [{
 *			src:"MyAudioSprite.ogg", data: {
 *				audioSprite: [
 *					{id:"sound1", startTime:0, duration:500},
 *					{id:"sound2", startTime:1000, duration:400},
 *					{id:"sound3", startTime:1700, duration: 1000}
 *				]}
 *			}
 *		];
 *		createjs.Sound.alternateExtensions = ["mp3"];
 *		createjs.Sound.on("fileload", loadSound);
 *		createjs.Sound.registerSounds(sounds, assetsPath);
 *		// after load is complete
 *		createjs.Sound.play("sound2");
 *
 * You can also create audio sprites on the fly by setting the startTime and duration when creating an new AbstractSoundInstance.
 *
 * 		createjs.Sound.play("MyAudioSprite", {startTime: 1000, duration: 400});
 *
 * The excellent CreateJS community has created a tool to create audio sprites, available at
 * <a href="https://github.com/tonistiigi/audiosprite" target="_blank">https://github.com/tonistiigi/audiosprite</a>,
 * as well as a <a href="http://jsfiddle.net/bharat_battu/g8fFP/12/" target="_blank">jsfiddle</a> to convert the output
 * to SoundJS format.

	/**
	 * The Sound class is the public API for creating sounds, controlling the overall sound levels, and managing plugins.
	 * All Sound APIs on this class are static.
	 *
	 * <b>Registering and Preloading</b><br />
	 * Before you can play a sound, it <b>must</b> be registered. You can do this with {{#crossLink "Sound/registerSound"}}{{/crossLink}},
	 * or register multiple sounds using {{#crossLink "Sound/registerSounds"}}{{/crossLink}}. If you don't register a
	 * sound prior to attempting to play it using {{#crossLink "Sound/play"}}{{/crossLink}} or create it using {{#crossLink "Sound/createInstance"}}{{/crossLink}},
	 * the sound source will be automatically registered but playback will fail as the source will not be ready. If you use
	 * <a href="http://preloadjs.com" target="_blank">PreloadJS</a>, registration is handled for you when the sound is
	 * preloaded. It is recommended to preload sounds either internally using the register functions or externally using
	 * PreloadJS so they are ready when you want to use them.
	 *
	 * <b>Playback</b><br />
	 * To play a sound once it's been registered and preloaded, use the {{#crossLink "Sound/play"}}{{/crossLink}} method.
	 * This method returns a {{#crossLink "AbstractSoundInstance"}}{{/crossLink}} which can be paused, resumed, muted, etc.
	 * Please see the {{#crossLink "AbstractSoundInstance"}}{{/crossLink}} documentation for more on the instance control APIs.
	 *
	 * <b>Plugins</b><br />
	 * By default, the {{#crossLink "WebAudioPlugin"}}{{/crossLink}} or the {{#crossLink "HTMLAudioPlugin"}}{{/crossLink}}
	 * are used (when available), although developers can change plugin priority or add new plugins (such as the
	 * provided {{#crossLink "FlashAudioPlugin"}}{{/crossLink}}). Please see the {{#crossLink "Sound"}}{{/crossLink}} API
	 * methods for more on the playback and plugin APIs. To install plugins, or specify a different plugin order, see
	 * {{#crossLink "Sound/installPlugins"}}{{/crossLink}}.
	 *
	 * <h4>Example</h4>
	 *
	 *      createjs.FlashAudioPlugin.swfPath = "../src/soundjs/flashaudio";
	 *      createjs.Sound.registerPlugins([createjs.WebAudioPlugin, createjs.FlashAudioPlugin]);
	 *      createjs.Sound.alternateExtensions = ["mp3"];
	 *      createjs.Sound.on("fileload", this.loadHandler, this);
	 *      createjs.Sound.registerSound("path/to/mySound.ogg", "sound");
	 *      function loadHandler(event) {
     *          // This is fired for each sound that is registered.
     *          var instance = createjs.Sound.play("sound");  // play using id.  Could also use full source path or event.src.
     *          instance.on("complete", this.handleComplete, this);
     *          instance.volume = 0.5;
	 *      }
	 *
	 * The maximum number of concurrently playing instances of the same sound can be specified in the "data" argument
	 * of {{#crossLink "Sound/registerSound"}}{{/crossLink}}.  Note that if not specified, the active plugin will apply
	 * a default limit.  Currently HTMLAudioPlugin sets a default limit of 2, while WebAudioPlugin and FlashAudioPlugin set a
	 * default limit of 100.
	 *
	 *      createjs.Sound.registerSound("sound.mp3", "soundId", 4);
	 *
	 * Sound can be used as a plugin with PreloadJS to help preload audio properly. Audio preloaded with PreloadJS is
	 * automatically registered with the Sound class. When audio is not preloaded, Sound will do an automatic internal
	 * load. As a result, it may fail to play the first time play is called if the audio is not finished loading. Use
	 * the {{#crossLink "Sound/fileload:event"}}{{/crossLink}} event to determine when a sound has finished internally
	 * preloading. It is recommended that all audio is preloaded before it is played.
	 *
	 *      var queue = new createjs.LoadQueue();
	 *		queue.installPlugin(createjs.Sound);
	 *
	 * <b>Audio Sprites</b><br />
	 * SoundJS has added support for {{#crossLink "AudioSprite"}}{{/crossLink}}, available as of version 0.6.0.
	 * For those unfamiliar with audio sprites, they are much like CSS sprites or sprite sheets: multiple audio assets
	 * grouped into a single file.
	 *
	 * <h4>Example</h4>
	 *
	 *		var assetsPath = "./assets/";
	 *		var sounds = [{
	 *			src:"MyAudioSprite.ogg", data: {
	 *				audioSprite: [
	 *					{id:"sound1", startTime:0, duration:500},
	 *					{id:"sound2", startTime:1000, duration:400},
	 *					{id:"sound3", startTime:1700, duration: 1000}
	 *				]}
 	 *			}
	 *		];
	 *		createjs.Sound.alternateExtensions = ["mp3"];
	 *		createjs.Sound.on("fileload", loadSound);
	 *		createjs.Sound.registerSounds(sounds, assetsPath);
	 *		// after load is complete
	 *		createjs.Sound.play("sound2");
	 *
	 * <b>Mobile Playback</b><br />
	 * Devices running iOS require the WebAudio context to be "unlocked" by playing at least one sound inside of a user-
	 * initiated event (such as touch/click). Earlier versions of SoundJS included a "MobileSafe" sample, but this is no
	 * longer necessary as of SoundJS 0.6.2.
	 * <ul>
	 *     <li>
	 *         In SoundJS 0.4.1 and above, you can either initialize plugins or use the {{#crossLink "WebAudioPlugin/playEmptySound"}}{{/crossLink}}
	 *         method in the call stack of a user input event to manually unlock the audio context.
	 *     </li>
	 *     <li>
	 *         In SoundJS 0.6.2 and above, SoundJS will automatically listen for the first document-level "mousedown"
	 *         and "touchend" event, and unlock WebAudio. This will continue to check these events until the WebAudio
	 *         context becomes "unlocked" (changes from "suspended" to "running")
	 *     </li>
	 *     <li>
	 *         Both the "mousedown" and "touchend" events can be used to unlock audio in iOS9+, the "touchstart" event
	 *         will work in iOS8 and below. The "touchend" event will only work in iOS9 when the gesture is interpreted
	 *         as a "click", so if the user long-presses the button, it will no longer work.
	 *     </li>
	 *     <li>
	 *         When using the <a href="http://www.createjs.com/docs/easeljs/classes/Touch.html">EaselJS Touch class</a>,
	 *         the "mousedown" event will not fire when a canvas is clicked, since MouseEvents are prevented, to ensure
	 *         only touch events fire. To get around this, you can either rely on "touchend", or:
	 *         <ol>
	 *             <li>Set the `allowDefault` property on the Touch class constructor to `true` (defaults to `false`).</li>
	 *             <li>Set the `preventSelection` property on the EaselJS `Stage` to `false`.</li>
	 *         </ol>
	 *         These settings may change how your application behaves, and are not recommended.
	 *     </li>
	 * </ul>
	 *
	 * <b>Loading Alternate Paths and Extension-less Files</b><br />
	 * SoundJS supports loading alternate paths and extension-less files by passing an object instead of a string for
	 * the `src` property, which is a hash using the format `{extension:"path", extension2:"path2"}`. These labels are
	 * how SoundJS determines if the browser will support the sound. This also enables multiple formats to live in
	 * different folders, or on CDNs, which often has completely different filenames for each file.
	 *
	 * Priority is determined by the property order (first property is tried first).  This is supported by both internal loading
	 * and loading with PreloadJS.
	 *
	 * <em>Note: an id is required for playback.</em>
	 *
	 * <h4>Example</h4>
	 *
	 *		var sounds = {path:"./audioPath/",
	 * 				manifest: [
	 *				{id: "cool", src: {mp3:"mp3/awesome.mp3", ogg:"noExtensionOggFile"}}
	 *		]};
	 *
	 *		createjs.Sound.alternateExtensions = ["mp3"];
	 *		createjs.Sound.addEventListener("fileload", handleLoad);
	 *		createjs.Sound.registerSounds(sounds);
	 *
	 * <h3>Known Browser and OS issues</h3>
	 * <b>IE 9 HTML Audio limitations</b><br />
	 * <ul><li>There is a delay in applying volume changes to tags that occurs once playback is started. So if you have
	 * muted all sounds, they will all play during this delay until the mute applies internally. This happens regardless of
	 * when or how you apply the volume change, as the tag seems to need to play to apply it.</li>
     * <li>MP3 encoding will not always work for audio tags, particularly in Internet Explorer. We've found default
	 * encoding with 64kbps works.</li>
	 * <li>Occasionally very short samples will get cut off.</li>
	 * <li>There is a limit to how many audio tags you can load and play at once, which appears to be determined by
	 * hardware and browser settings.  See {{#crossLink "HTMLAudioPlugin.MAX_INSTANCES"}}{{/crossLink}} for a safe
	 * estimate.</li></ul>
	 *
	 * <b>Firefox 25 Web Audio limitations</b>
	 * <ul><li>mp3 audio files do not load properly on all windows machines, reported
	 * <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=929969" target="_blank">here</a>. </br>
	 * For this reason it is recommended to pass another FF supported type (ie ogg) first until this bug is resolved, if
	 * possible.</li></ul>

	 * <b>Safari limitations</b><br />
	 * <ul><li>Safari requires Quicktime to be installed for audio playback.</li></ul>
	 *
	 * <b>iOS 6 Web Audio limitations</b><br />
	 * <ul><li>Sound is initially locked, and must be unlocked via a user-initiated event. Please see the section on
	 * Mobile Playback above.</li>
	 * <li>A bug exists that will distort un-cached web audio when a video element is present in the DOM that has audio
	 * at a different sampleRate.</li>
	 * </ul>

	 *
	 * <h4>Known Browser and OS issues for HTML Audio</h4>
	 * <b>All browsers</b><br />
	 * Testing has shown in all browsers there is a limit to how many audio tag instances you are allowed.  If you exceed
	 * this limit, you can expect to see unpredictable results. Please use {{#crossLink "Sound.MAX_INSTANCES"}}{{/crossLink}} as
	 * a guide to how many total audio tags you can safely use in all browsers.  This issue is primarily limited to IE9.
	 *
     * <b>IE html limitations</b><br />
     * <ul><li>There is a delay in applying volume changes to tags that occurs once playback is started. So if you have
     * muted all sounds, they will all play during this delay until the mute applies internally. This happens regardless of
     * when or how you apply the volume change, as the tag seems to need to play to apply it.</li>
     * <li>MP3 encoding will not always work for audio tags if it's not default.  We've found default encoding with
     * 64kbps works.</li>
	 * <li>Occasionally very short samples will get cut off.</li>
	 * <li>There is a limit to how many audio tags you can load or play at once, which appears to be determined by
	 * hardware and browser settings.  See {{#crossLink "HTMLAudioPlugin.MAX_INSTANCES"}}{{/crossLink}} for a safe estimate.
	 * Note that audio sprites can be used as a solution to this issue.</li></ul>
	 *
	 * <b>Safari limitations</b><br />
	 * <ul><li>Safari requires Quicktime to be installed for audio playback.</li></ul>
	 *
	 * <b>iOS 6 limitations</b><br />
	 * <ul><li>can only have one &lt;audio&gt; tag</li>
	 * 		<li>can not preload or autoplay the audio</li>

	 * 		<li>audio sprites can be used to mitigate some of these issues and are strongly recommended on iOS</li>
	 * </ul>
	 *
	 * <b>Android Native Browser limitations</b><br />
	 * <ul><li>We have no control over audio volume. Only the user can set volume on their device.</li>
	 *      <li>We can only play audio inside a user event (touch/click).  This currently means you cannot loop sound or use a delay.</li></ul>
	 * <b> Android Chrome 26.0.1410.58 specific limitations</b><br />
