[GraphHopper] GraphHopper Weighting

[Moises Arcos]

Thank you for your answer.

I followed your instructions and I used the initCHPrepare method to update
the edges list.

But I have another trouble: When the list is updated, there isn't any edge
that is inside my list.
I mean that in the method calcWeight [1] not found any edge that is the
same than another. This condition is always false.

¿How do I know if I'm selecting the right edge? I used the location index
[2]

Regards!!!
