[GraphHopper] Shortest route (not fastest) from Paris to Rome

[Geoffrey De Smet]

Thanks Peter :)

Actually, we're not after more alternative routes, but the absolute 
shortest.
It's for a theoretical case - in a VRP to minimize absolute road distance.
We'll compare it with a variant, for which we use the default routes and 
minimize time distance.
The second variant is the practical case.
