Socket event hub

socketEventHub.js

// This helper will guide our websocket events to freezer
function toFreezer( socketEvent, freezerEvent ){
  socket.on( socketEvent, function(){
    var args = [freezerEvent].concat( Array.from(arguments) );
    freezer.emit.apply( freezer, args );
  });
}

// Now we can redirect socket events easily
toFreezer('messageReceived', 'message:received');
toFreezer('friendshipAccepted', 'friend:add');
toFreezer('friendOnline', 'user:add');
