	Observer ()=default
	Constructs unregistered instance of Observer class.
	Observer (const ClusterGraph *R)
	Observer (const Observer &copy)=delete
	If you want to copy a subclass of Observer, call the default Observer() constructor and optionally also call reregister if it makes sense.
	Observer (Observer &&move)=delete
	If you want to move a subclass of Observer, call the default Observer() constructor and optionally also call reregister if it makes sense.

	Destroys the instance, unregisters it from watched instance.
const ClusterGraph *	getObserved () const
Observer &	operator= (const Observer &copy)=delete
Observer &	operator= (Observer &&move)=delete
virtual void	registrationChanged (const ClusterGraph *old)
	Called after reregister() changed the observed instance.
void	reregister (const ClusterGraph *obs)
	Associates observer instance with instance obs.

Detailed Description

Abstract base class for cluster graph observers.

If a class needs to keep track of changes in a clustered graph like addition or deletion of clusters, you can derive it from ClusterGraphObserver and override the notification methods clusterDeleted, clusterAdded.
