server handles multiple users connecting to the server. client just sends message to server. Concats user derfined user name to the front of the msg, client-side. this should be handled server side to avoid clients connecting with the same name. server uses unblocking sockets, meaning it polls to see if someone has connected. if not, it throws an exception. the exception is caught and we go on to the reception of messages. if none are received from a particular client, we catch the exception and continue to  the next client.
Need to next relay the message, that one client sends
, to all of the other clients
added some comments to client.py and server.py
