[GraphHopper] Load a custom edge weight

[Rossano Schifanella]

That was the problem! I didn't specify the vehicle with setVehicle when 
a GHRequest was created.

I have another quick question: is it possible through the LocationIndex 
or something similar to have for each edge in the graph the coordinates 
(lat, lon) of the end points?

Thanks!
Rossano
