Changed from Set to ArrayList
Added debug TAG variable for easier debugging. Testing fix for negative
route stops in specific instances.
Working on the direct route and indirect route algos.
Checking my changes so far. Crufty code but appears to work.
getExtendedRoutes has been augmented to return a String[] where each
item in the array is a recommendation for the user to take an indirect
route to get to their destination.
Ugly but working-ish code for finding indirect stops.
