[GraphHopper] TurnCosts for CH

[Peter]

Hi,

different edges.

The search will be edge based and so the edges will be identical.

There is an issue for this #270, where we list the major problems with
turn costs and CH. This requires knowledge with CH and also some GH
internals. I guess this will take us roughly 2-4 full time weeks. As
this is relative unattractive long but very important (for us too) what
do you think about a crowd funding campaign?
Where every company in the need could sponsor us with only a fraction of
the costs. (And we would also sponsor the majority of our time for this)

Do not hesitate to contact me off-list if you or others are interested!

Kind Regards,
Peter
