#2229

• The IVRPData now specifies an optional BestKnownTourVehicleAssignment property. This can be used for solutions where a specific assignment for tours to vehicles is necessary.
• The VRPInterpreter interpret the new BestKnownTourVehicleAssignment directly as VehicleAssignment in the created PotvinEncoding.
• Minor refactoring in (I)VRPInstanceProvider.
