Major refactoring. Delete Robolectric tests and implement them as regular Android Unit Tests. Refactor some of user interface.
Modify the way that airports, colleges, and transporation preferences are stored. Store them as enums so that they can easily be translated to and from the database.
Refactor the date and time pickers out and into a dseparate fragment. Flesh out the Group and WallPost models so that we can use them in Parse when the time comes.
Merge branch 'master' of github.com:minhtrangvy/AirportTeleport into parse-integration
