Class JSUTILS.EventDispatcher
The EventDispatcher class mimics the DOM event dispatcher model so the
user can add and remove event listeners in a familiar way. Event bubbling is
not available because events are dispatched in relation to state changes of
physical components instead of layered graphics so there is nothing to bubble up.
Defined in: EventDispatcher.js.
