Events mixin

| Method | Description | | ----------------- | ------------------------------------------------------------------------------------ | | on | Registers event(s) callbacks | | once | Registers event(s) callbacks which will be invoked once | | off | Removes registered callbacks | | listenTo | Registers event(s) callbacks for given emitter | | listenToOnce | Registers event(s) callbacks for given emitter which will be invoked once | | stopListening | Removes registered callbacks for given emitter | | trigger | Triggers registered event's callbacks | | triggerMethod | Triggers registered event's callbacks and invokes emitter's event associated methods | | getOnMethod | Returns event associated method if any. Feel free to override to provide own logic |

setInterop method

Use this method for defining interop behavior. Also there is a default one which tries to use emitter's on and off.
