[ ] Factor most of the current mingl into background_services - these access all things twitter and neo4j
[ ] Delete methods from background_services that have been excluded from the new API: get_followers, get_friends, get_relations
[ ] Make hydrate_users private and possibly refactor it back with _hydrate_users_from_twitter (eventually there may be another layer between neo4j and twitter stored in Cassandra!)
[ ] Clean up testing because it references a "mingl" which will now be background_services. It event references a mingl_bot
[ ] create proper init.py that only imports stuff that belongs
[ ] do something smart with testing so that it's better organized and isolated from the other code
[ ] create a readme that helps orient new developers
[ ] the foreground_services will eventually become the mingl API - rename it accordingly (maybe it should be called mingl)
[ ] move ipython notebook files into a better place
