[GraphHopper] Route Options and Directions Mode

[Muhammad Babar]

And also if i set the CH off then will this guarantee to work?

GHRequest.setWeighting "fastest" or "shortest"

And does we only have two options fastest and shortest?

Also setting CH off also reduces the graph size! Right?

Many Thanks
Muhammad Babar
