An event listener associates a callback function with a specific event.
The system.events.EventListener interface is the primary method for handling events. Users implement the system.events.EventListener interface and register their listener on an system.events.IEventDispatcher using the addEventListener. The users should also remove their system.events.EventListener from its system.events.IEventDispatcher after they have completed using the listener.
