This class describes the interface of alterable directed graphs. It extends BaseDigraphComponent with the alteration notifier interface. It implements an observer-notifier pattern for each digraph item. More obsevers can be registered into the notifier and whenever an alteration occured in the digraph all the observers will be notified about it.
