Starting to break things apart into separate files.  Trying to make the code easier to follow, but I'm still not sure if I'm there yet.
Additional commenting and initial work with Twitter API
Major refactoring.  Split app.js out into multiple libraries.  Much more modular now.  Still have to clean up instagram and twitter lib files, I don't think they're necessary.
Streaming from Instagram and Twitter simultaneously based on a non-hard coded keyword
Added slideshow code back in.  First fully functional commit.
