app.js vs app.js

Hello BtFord!
I worked a lot with your seed/skeleton projekt. It is really great. Thank you for providing it. Just one feedback from the point of view of a learner: You have two app.js files on your projekt. One is the express server (backend) and the other one is the angularJS (frontend) single page application. You should rename the first one to something like server.js so that others don't get confused as I did.
