function

Adds a socket event listener.

`server.on(event, handler)`

Adds a socket event listener.

server.on("notifications", function(data, ackFn){
  console.log("Received " + data);
  ackFn("Acknowledged, thank you");
});

event {string}:
The name of the socket event to listen for.
handler {SocketEventListener()}:

server.on({
  "news": handleNews,
  "tweets": handleTweets,
  "users": handleUsers
});
