/**
*
* Mediator encapsulates how a set of objects ({@link PartyMember}) interact. Instead of
* referring to each other directly they use a mediator ({@link Party}) interface.
* The Mediator pattern defines an object that encapsulates how a set of objects
* interact. This pattern is considered to be a behavioral pattern due to the way
* it can alter the program's running behavior.
* <p>
* Usually a program is made up of a large number of classes. So the logic and
* computation is distributed among these classes. However, as more classes are
* developed in a program, especially during maintenance and/or refactoring,
* the problem of communication between these classes may become more complex.
* This makes the program harder to read and maintain. Furthermore, it can become
* difficult to change the program, since any change may affect code in several
* other classes.
* <p>
* With the Mediator pattern, communication between objects is encapsulated with
* a mediator object. Objects no longer communicate directly with each other, but
* instead communicate through the mediator. This reduces the dependencies between
* communicating objects, thereby lowering the coupling.
* <p>
* In this example the mediator encapsulates how a set of objects ({@link PartyMember})
* interact. Instead of referring to each other directly they use the mediator
* ({@link Party}) interface.
