public class CropGTFS
extends Object
Remove all stops outside the bounding box,
then remove all stop_times outside the bounding box,
recording all trips with two or more stop_times inside the bounding box.
Then remove all trips with no stoptimes or one single stoptime,
then remove all transfers whose stops have been removed.
Note that this does not crop the GTFS shapes, only the stops and stoptimes.
Therefore in some tools like Transport Analyst, the data set will appear to extend beyond the bounding box
because the entire shapes are drawn.
