- * 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> 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>
