[GraphHopper] the distance from the current location to the path

[Peter K]

Hi Dmitrie,

you could calculate the distance to every (close) edge of the path.

See the code I'm using in Location2NodesNtree.checkAdjacent ->
DistanceCalc.calcNormalizedEdgeDistance

Before you can use this method you have to check if you should use the
distance to the end points of the edge or if you should use the
perpendicular edge distance. This is done via DistanceCalc.validEdgeDistance

Kind Regards,
Peter.
