[GraphHopper] Bearing at routing

[Peter]

No, can't find the workaround but it was related to a special weighting
class I think with an edge check (read further ;)).

You'll have to do some modifications to the QueryGraph where one
normally inserts a virtual node for the query point (the
snapped-to-road-point) and you add some virtual edges. Now using the
bearing you can avoid inserting some of the edges OR increase the weight
for them OR create a special weighting class which increases the
weighting if you encounter those virtual edges.

E.g. in TurnWeighting we check for a U-turn like this:
if (turnCosts == 0 && edgeId == prevOrNextEdgeId)
            return weight + defaultUTurnCost;

you'll have to detect now this special U-turn and do a similar thing I think

Regards,
Peter.
