[rules-users] Planner: Vehicle Routing, but with return to home after last delivery

[jimirn]

I am not sure I understand how the rule works.

I have several DeliveryPlace's (VrpCustomer's) that don't have
previousAppearance == $customer, basicly it is only the first DeliveryPlace
on a route that has this for a certain Consultant (VrpVehicle).
