Move a Connection into a Socket Set

Demonstrates Socket.TakeSocket, which moves a connection into a newly created member of this object's socket set. After one or more calls, the object acts as a set of sockets.

Background. A socket set groups multiple connections so they can be monitored together with the SelectForReading and SelectForWriting methods. After success, the source socket holds no connection.
