Documentation

This the class that represents a unit of work.
The task consits of two main components. The "work" to be done, and the "result" of the completed task. In order to create an application, the user must specify methods for packing and unpacking both the "work" and "result" portions of the task. The user is not responsible for initializing the send or for packing the task's number
When the task is being serviced by a worker, it contains a link to the ID of that instance of the worker.
