/**

The MSocketFactory class provides an API to obtain connected sockets. There

are two methods of obtaining these connected sockets. The first is via a

listening service on a specified local port that receives connections. The

second method is a connecting service that initiates a connection to a 

specified port on a specified remote host.

The connecting service also requires an observer - an MSocketConnectObserver.

There can be many connecting services active at any one time. Each one has

an associated socket connector - MSocketConnector. This API allows each 

connection request to be stopped at any time before the connection ends. The

connection is ended when the socket connect observer has been notified of 

either a successful connection or of an error occuring during the connection.

Attempting to stop the socket connector after either of these notifications

will cause an access violation - the socket connector is no longer valid.
