* @version $Id$
*
* Description: FGMultiplay is an FGProtocol object used as the basic
* interface for the multiplayer code into FlightGears generic IO
* subsystem.  It only implements the basic FGProtocol methods: open(),
* process() and close().  It does not use Sim Gear's IO channels, as
* the MultiplayMgrs creates their own sockets through plib.
*
* It will set up it's direction and rate protocol properties when
* created.  Subsequent calls to process will prompt the
* MultiplayMgr to either send or receive data over the network.
*
