Detailed Description

Example of using the Mediator Pattern in C#.

A mediator is instantiated then populated with users and groups. Users are added to some of the groups.

A series of operations are then performed through the mediator. The output shows the results of each operation. Note that all operations are done using user and group names, with no knowledge of the actual lists of users and groups. The mediator hides all the details.
