Class Listener

Known Subclasses:: KeyListener, MouseListener

An input dispatcher that listens for a specific type of input event, and when it occurs, calls a callback function. Different subclasses of Listener are used to listen for different input event types.

Each listener has a priority, which determines the order in which listeners are consulted. For each event, the relevant listener with the highest priority will be the only listener notified for that event.

	`__cmp__(self, other)`
	`handle(self, event)`
	`is_relevant(self, event)` Return true if this listener's callback should be notified about the given event.
