Initial Commit
-Basic send/receive working: when a line is typed in any client or the
server, it is sent to every other party. The party that sent the line will
see the line twice because in its current stage everyone receives the
line, including the sender itself.
-Server should be started first, followed by client(s).
-To terminate, stop the server first, and then enter "END" in the clients.
In future commits clients will be able to pull out before the server ends
without causing "null"s to be printed.
