In the pythons extensions section let's create a new "transit" edge provider. It takes a gtfs file. The edge expansion specification follows: [Contains lat/lon/time] -> for every nearby stop, a vertex with stop_id, and time at arrival [Contains stop id] -> for every vehicle departure in the next X hours, a vertex representing being on the vehicle moments after boarding.
