Handling activities are now determined to be significant to the delivery of the cargo based on the logical order, not the reported completion time.

Introduced the LegMatch concept that describes how an activity matches a leg of an itinerary.

Moved scenario tests to inside the domain package (but still in the test source folder of course).
