Detailed Description

Implements TCP networking.

This class implements TCP/IP data connections. Nagle algorithm is turned off, to speed up little but frequent transfers.

 TcpCx* cx = new TcpCx;
 Packet* p;

 cx->connect("localhost", 4242);
 if (!cx->poll(5)) {
   delete cx;// connection failed
   return;
 }
 cx->send(Packet(CX_INIT, 1));
 if (!cx->poll(5)) {
   delete cx; // can't receive anything
   return;
 }
 p = cx->receive();
 delete cx; // close connection

		int	port
	)
