-Removed the retransmit boolean variable from updateModel
-Removed the notifyModelSubscribers from the updateModel method

worker class after a model is recieved, this gives us the flexibility to

and sends the new model out to everyone.  This eliminates race
conditions
-Also put updateModel call and sendObject inside synchronizes statements
-Added common WarCardGameBoardView
-This version runs
