Modified how the program works so that it can have persistence variables.  The new TripVars class creates a Serializable construct that I can stash variables in.  The ActivityRecognitionService now doesn't do much other than register an Intent(ActvityRecognitionIntentService) with the system to get updates about what you're doing.  All the business logic to track what you're doing and record it is now in that class.  This is the last commit before I rip out a huge amount of old cruft so that I can clean all of this up.
