// TimeStamp: 1/30/02 -- 3:02pm
// Author: Ken Anderson
// Relation: This file so far is only related to Freespace and has no purpose for
//           external functions.
// Purpose: Using Winsock2, this class encaspulates client functions for the system
//          to communicate with the server it is logged on too.  Currently the system
//          only handles ports to mucks, this will be updated to allow all data to be
//          translated into this world.  In addition this function will work in 
//          combination with Freespaces World.cpp to allow viewing screens to connect
//          to multiple places at anytime.
//
// Upgrade Notes: NONE
