Add "Follow" feature? #7
Description
Grab the timetable, find the stop of interest, find the stop number for the one just before that stop, watch the user's chosen bus to see when it reaches "Due" or disappears from that stop & post a notification.
Difficult, given my skill level with iOS - requires polling, background workers, notifications. Difficult also in general; usefulness varies depending on distance between stops at point of engagement and there appears to be no API access for timetables, leading to screen scraping of some pretty heavy HTML - potentially very fragile.
