Two players can connect to the server and play against each other. Uses cowboy as the server layer to allow for multiple protocols (raw sockets, websockets and possibly later other http push technologies as fallback)
You will need to have git installed (to fetch the cowboy server dependency) as well as Erlang, of course. Simply go to the main directory and type:
make
