Allow matching to ignore direction

[karussell]

Often the direction of a recorded track is not known or hard to determine. For those cases add a "ignore_direction=true" option

When?

A Track Segment holds a list of Track Points which are logically connected in order.
(GPX spec)

I think if a user indeed has a track which may be reversed, I would entice them to solve that on the client side and try the track in either direction.

When?

I think this could be just a user requirement, or wrongly mapped stuff or e.g. for bike people sometimes ignore oneways

This is not always possible if I remember correctly the examples I had, as you can have this road:

A--->---B----<----C

and now a track that goes from A to B to C.

But we can also close here for now and reopen if we get real world examples.

Oh, I see that, but that would be a new vehicle in my book, not a changed map-matching algorithm.

Yup.
