Detailed Description

template<class LISTENER_CLASS>
class grinliz::Publisher< LISTENER_CLASS >

A Publisher communicates to a Listener by calling its methods.

If a publisher is deleted, it will clear the pointers to its listener, and if a listener is deleted it will clear the pointes to its publisher. Therefore they can have independent lifespans.

A publisher is aggregated into the class that wants to publish:

	class Switch
	{
		Publisher<SwitchListener> publish; 	
	}
