Detailed Description

Class to handle the connections an application can have.

There are two different modes:

• A client mode: The application has a server to which it talks.
• A server mode: The application has (potentially) various clients it talks too.

Of course an object can switch between the states, in which case the previously created connections are closed and removed.
