fixed bug with resetting the app after a trip has reached its last stop
added a check to map view controller - if it is current window when the app reloads then it checks NSUserdefaults to see if it has a trip session active or trip session over
removing comments
adding error functions
bug fixes
train less at the moment, but more stable
bug fixes:  some wmata stop id’s are 0 if they are the final stop in a route so core data fetches were returning random stops that were 0
annotation images were not being set correctly - now the image setting code is placed in the MKAnnotationView viewForAnnotation redrawing method
tuned the location manager to only kick into high level detection when the user is getting very close to the final stop
