Created MapActivity, MapFragment, & ForegroundLocationService

[BlakePatterson]

• MapActivity, MapFragment, & ForegroundLocationService have been created and the basic logic for each has been implemented.
• The ForegroundLocationService has been completed and all the logic to start it in the Foreground and control it from the MapActivity has been completed.
• The ForegroundLocationService receives updates every 5 meters (I think this is fine for now but we should all talk about what this update condition should be)
• The ForegroundLocationService is stopped in the onDestroy() of the MapActivity, again this is a temporary solution and we can discuss when we actually want to stop the service later.
• The MapFragment is mostly set up, with the basic methods for updating the map view & marker location complete.
• All interfaces for communicating between the three components are set up
