Initial Upload

Status Bar Functions but needs more formatting
Times are correct, lists last update time
NEXT STEPS:
Add app GUI for selecting stops, currently hardcoded. Shouldn't be too
bad given nextBus API. Will need new class for fetching and building
dropdowns.

LATER PLANS:
GUI options for controlling number of stops shown
Option to have one stop use GPS to choose the closest stop
Tap to refresh
Choose time interval of refresh (currently does on screen on and once a
minute)
