[Imports] Bus stop import in Raleigh area of North Carolina, USA

The map matching is an interesting idea: I think OSRM can return a list 
of OSM node_id's from a matched route and it should be able to handle 
one-ways fairly well, giving you the 2+ distinct directions for PTV2 
tagging. You would just have to work backwards from the node_id's up to 
the way_id's to build a relation of ways. The big obstacle I see to this 
is that often highway ways need to be split strategically where routes 
turn, end etc.

Still, just building relations from whole ways could be a good starting 
point for a big network import. Adding ordered stops to the route 
relations would be easy conceptually, but any splitting of the ways 
would need to be done manually.
