Create Inbound Shipment Plan
Plans inbound shipments for a set of items.  Registers identifiers if needed,
and assigns ShipmentIds for planned shipments.
When all the items are not all in the same category (e.g. some sortable, some
non-sortable) it may be necessary to create multiple shipments (one for each
of the shipment groups returned).
