You will be creating a program that implements the Observer design pattern. This design pattern is utilized in almost all GUI systems and is the basis for distributed event handling. The goal of the program is to create a class (the Subject class for this assignment) that has a private variable (address) that can be modified via a standard mutator function (setAddress). This class has additional member functions that allow other classes (the observers) to register and deregister themselves with the Subject. If observers are registered with the subject, they will receive notifications (via a callback function) if the subject's address ever changes.
