+ *
+ * A group of objects that receives a shared animation state.
+ *
+ * Usage:
+ *
+ * 	-	Add objects you would otherwise pass as 'root' to the
+ * 		constructor or the .clipAction method of AnimationMixer.
+ *
+ * 	-	Instead pass this object as 'root'.
+ *
+ * 	-	You can also add and remove objects later when the mixer
+ * 		is running.
+ *
+ * Note:
+ *
+ *  	Objects of this class appear as one object to the mixer,
+ *  	so cache control of the individual objects must be done
+ *  	on the group.
+ *
+ * Limitation:
+ *
+ * 	- 	The animated properties must be compatible among the
+ * 		all objects in the group.
+ *
+ *  -	A single property can either be controlled through a
+ *  	target group or directly, but not both.

+	 * 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+).

+	 *      <LI> start: Optional, 0-1 : Initial position, default 0 except for when continuing along the same path.</LI>

+	 *      <LI> orient: Optional, string : "fixed"/"auto"/"cw"/"ccw"<UL>
+	 *				<LI>"fixed" forces the object to face down the path all movement (relative to start rotation),</LI>
+	 *      		<LI>"auto" rotates the object along the path relative to the line.</LI>

+	 * information on these objects in the background and sharing them can cause unexpected behaviour. Values
+	 * outside 0-1 range of tweens will be a "best guess" from the appropriate part of the defined curve.
