Heroku deployment

Great work! Just thought it'd be great if some instructions can be included in the readme for how to deploy using heroku, more specifically, was wondering how to make React talk to the right express server? Thanks!

I've looked at deploying a similar thing to this and would also be interested in how you've got Heroku to play nicely with this approach. I've given it a go, and without a top-level package.json, Heroku doesn't seem to like deploying this frontend and server in a single go!

I've used the alternative, split my project in to front and back, and deployed each individually.
