PxEventObserver: Handle events fired by a subject

Interface that should be implemented by objects that want to be notified about events. When you want to listen

the method PxEventSubject::attach() method and register an object that will be notified when a certain event
occurs. The object that you want to attach to the PxEventSubject should implement this PxEventObserver
interface.
