Feature request: Support for OSM editing

[hbruch]

We use pfaedle to enhance the VVS (Stuttgart, Germany) GTFS feeds.
However, we get some complaints where the deduced route does not match the real route.

If I read the code correctly, pfaedle would profit from maintained route relations in OSM(?).

To help gathering these, pfaedle could ease the rather tedious creation/maintenance of OSM route relations, if there were an option to generate route relations with OSM way Ids.

Helpful would be as well a report listing the GTFS stop id associated with the matched OSM stop ID.
