Issue #013: Reformatting in preparation for upload to Heroku.
Issue #013: A first attempt at checking the UH Course Availability website to see if it is necessary to notify users; this will fail since the courses_to_email method is never called anywhere, but future development can try to use the method.  Issue #030: Assuming that the courses_to_email method is called, the application should now update the database with the new number of seats.  It might also be worth considering how to update the other fields since data like the classroom might change as well, though that is not strictly the goal of this application.
