Lots of goodies

When a bus arrives (simulated at present) the app asks the user if they are getting on the bus.
If they say "yes", the app starts publishing the bus' coordinates from the device (publishing is currently stubbed).
The user can choose to stop tracking and quit.
If the user is OK with being tracked, they can hit "hide and continue" and the app will "minimize"
Upon opening, the app shows the closest bus stop (simulated).
The user can enter a new bus stop number if this one is not correct (publishing is stubbed)
