Your assignment is to write two programs, a client and a server.  The clients play the game 'subtract'.
The server keeps track of the state of the game, and sends changes to all clients.

Rules to subtract:
	(1) The total starts at 25.
	(2) Anyone can at any time subtract a number (1 .. 5) from the total.
	(3) No player can go twice in a row.
	(4) The winner is the last person to do a subtraction.
	(5) You cannot make the total go below zero.


The client connects to the server.
It shows the current total, updating whenever needed.
It communicates all subtracts to the server.
It shows if you are currently winning or losing.


The server accepts connections from the client (no more than 100).
It updates the total to all valid clients.
It handles client disconnects.

Either the client or the server enforce each of the four rules.

This is out of 13 points, one for each rule, one for each client task, and one for each server task.  You lose one point
per day after Thursday Oct 3th.
