   Routing Style
     
     Fastest: Computes the least cost route, considering road class.

     NoFreeways: Computes a route without considering limited acccess roads (Freeways/Highways/Motorways)
     MoreFreeways: Favors freeways even if less costly routes are available.
     AvoidFreeways: Assigns a high cost to travel on limited access roads, so that they are used only if necessary to find a route.
