quick fix for env variables.

1. Found redundant models (the weird collapsable code option was hiding it...so I deleted redundancies)
2. Quick fix for use of environmental variables is specifying when you are hosting locally or via heroku.  (located on line 23). I'm going to cookies and code on Wednesday to ask Nate how to do vagrant env stuff. looks like some pretty simple ruby syntax I just don't have time right now.
