App can connect to Facebook via Oauth but no functionality.

App can connect to Facebook using the facebook_oauth gem.  However, break to add in analytics because not sure that Facebook data that I want is available via the facebook API.  Will look into this later.  Currently app is set up to integrate Facebook login later.

Removing sign in with facebook button.
