Build Delivery Snapshot use case. This is a subfunction level use case (see Cockurn 2001) supporting user-goal level use cases like {@link BookNewCargo} by returning a Delivery snapshot Value object.A Delivery snapshot describes all we know about the current shipping status of a Cargo. It's the heart of the application domain knowledge. The Delivery snapshot is derived from one of the 3 overall stages a Cargo shipping can be in: 1) Cargo is being created (Route Specification is known) 2) Cargo has been routed (Route Specification + Itinerary is known) 3) Cargo is in transit (Route Specification + Itinerary + last Handling Event is known) Code is organized along the contours of the process flow of cargo shipping instead of the data structures. This makes it easier to reason about a certain step in the shipping process (use case) according to the intuitive understanding of the shipping domain. @see RouteSpecification plays a (methodful) Role of a factory that coordinates the Delivery build. @see HandlingEvent plays a (methodful) Role that coordinates deriving data from the last Handling Event. @see Itinerary plays a (methodful) Role supporting the other two roles with Itinerary calculations.
