(feat) Added server.js socket logic and call to socket-io client library...

... in index.html

This doesn't break anything - it has been tested on code from master repo. At present index.html isn't pinging the socket even though the node server is running. It's something to do w/ the socket-io client dependencies because the same server.js code works w/ my dummy index.html file.

You're up @allenjprice  :)
