-1. ---IN PROGRESS--- Implement the multiplayer aspect of the game - detect if M_CLIENT or M_SERVER is set, and perform appropriate actions (e.g. M_CLIENT could control left paddle, M_SERVER could control right paddle).
-2. ---- SHOULD BE DONE ---- Fix decoding function - segfaults if code is invalid.
 3. Try to make the ball go between screens.
-
-4. ALMOST DONE - Add better exception throwing and handling
-5. Finish adding comments for the other files.
-6. ---DONE--- Fix the 'sendAll' and 'recvAll' methods in Sock. Instead of calling the parent function with a parameter in the children functions, set a variable in the children functions (set it to a different value in the 'Client' implementation and the 'Server' implementation). This variable can be accessed by the parent method, and it can perform the appropriate action
-7. Add code to handle the positions received by client and paddle. Also, make the server send the ball position each time, and have both client and server send a message if the game is quit.
+8. Have both client and server send a message if the game is quit.
