inherited overrides trigger(event)

This function causes an event to happen. This will then cause any event listeners that are waiting for that event, to get called. If there are no event listeners for an event then nothing will happen.

If the name of the Event that is being triggered is in EventTarget.allowedEvents_. Trigger will also call the on + uppercaseEventName function.

Example: 'click' is in EventTarget.allowedEvents_, so, trigger will attempt to call onClick if it exists.
