Added normalize.css, browserify bundle.js, set up http server.
Remove normalize.css, set up form.
Set up socket.io and socket.io-client.
Set up custom event to be emitted by socket.io client when a message is sent, set up socket.io (server-side) to listen for that message event.
Set up socket.io (server-side) to emit messages to all connected clients upon receiving a message event, set up socket.io-client to append the data passed along by the message event to the DOM upon receipt of a message event.
When the message form is submitted the message event is no longer emitted to all connected clients, rather the message event is broadcasted to all clients that are not the sender.  The client sending the message simply appends its message to the DOM directly.
