[GraphHopper] State and Province crossings

[Tim g]

 - Sorry for the extremely delayed response, but I just wanted to say I
appreciated the feedback, and thank you for your advice Nicolas! - It
turned out I had missed a call available in the API of a commercial mileage
engine the company I work for was already using and licensed for, so
(unfortunately?) I didn't get a chance to pursue this with graphhopper.  -
I was looking to overlay a route over an openstreetmap (which this looked
to be a great solution for!), with in-state distances, but had missed the
commercial product actually had a .dll method available to pull the route
shape points to be able to render it elsewhere, which took care of the
whole issue and made a quite easy solution with things I had previously
built.   --  I hope to have a reason to return to the graphhopper project
thought, after having it up and running it looks pretty awesome, especially
in the speed department.

Thanks again,
  ~Tim
