Currently, the DistributionCarrierScheduler creates one or more* carrier_s_ to distribute the incoming LSPShipments.

IMO this does not make sence, because it should be only one carrier, which can decide on its one, which LSPShipments were put in which tour. --> Need for an pickupTimeWindow, with earliest pickuptime = arrivalAtHub + handlingDuration in hub.
This is only possible with CarrierShipments, which has TimeWindows for Pickup and Delivery.

This will have consequences in the whole setup, because also the ScheduledShipmentLoad, ScheduledShipmentTransport, ScheduledShipmentUnload must accept CarrierServices (as is) OR CarrierShipments (missing).

Going from there, I expect the need for follow-up adaptions... argh :(

(( I started with it on branch: kmt_makeDeliveryUsingCarrierShipments ))

Re-start working on this now....
As a first step, a new configGroup is added, allowing to set desired behavior. Default setting is "serviceBased" (see #261 )

To reduce the complexity, I am now checking, where the CarrierService is really needed (and why) in: ScheduledShipmentLoad, ScheduledShipmentTransport, ScheduledShipmentUnload. If I can rid of it there, it gets at least a bit less complex...
