public interface IsObservable

An interface to be implemented by AIDA objects that can notify observers of change to their state. The interface is designed to add minimal overhead to objects which are observable, whether they are observed or not. Since objects such as histograms may be updated very frequently they will generally only send one notification to observers. If the observer needs to be notified again it must call setValid before another notification will be sent.
