Interface WorkerContract

This interface enforces the methods required for a valid library object. These methods may be manually honored, or may be satisfied by using the corresponding library trait. Traits that extend upon this functionality should be expected to implement this for you.

Workers provide an approach to accomplishing a task within a narrow scope to a manager, who is tasked with awareness of all related scopes and appropriately delegating the request as needed to the correct one. This allows for maximal abstraction and easy extension by simply adding new use case workers to the known pool of handlers.
