Detailed Description

Represents a Subject that takes observers implementing the IObserverNumberChanged interface.

In more complex systems, an interface like this might have multiple subscribe/unsubscribe methods for different kinds of observers. For C#, such multiple methods might actually be one Subscribe/Unsubscribe method that uses overloading to take different observer interfaces.

This interface is use to ensure the Subject implements all the necessary methods to support observers.
