    Description

      For Vehicle Routing and project job scheduling users want to use this model:

      @PlanningEntity // No longer a shadow
public class  Vehicle {
   @PlanningVariableCollection(type = DISTINCT_LIST)
   List<Customer> customerList; // genuine!
}

@PlanningEntity // Now a shadow
public class Customer {
  @AnchorShadowVariable Vehicle vehicle;
}

      Although this might have a small performance loss in basic setups (think 2opts on not-anymore linked lists), it might have a lower gain too (think pillar and subchain swaps)
