Subject: [PATCH] Refactor POS PurchaseOrder application domain model class to
 include an identifyAs(:Long) builder method to set the ID of a PurchaseOrder
 instance.

Annotate the PurchaseOrder class with Jackson's JsonTypeInfo annotation.

Include statically defined Array and Map instance members for test purposes.
