-----------------------------
Thanks for applying the patch quickly. Didn't realize I had forgotten to close the issue out.

> Inital working draft of support for "actor" assignments from business process definitions. All current code hard-codes task assignments in the Task code and ignores the /process-model/graph/nodes/node/actors/actor element. This code provides one working approach to supporting this originally intended but unimplemented functionality.
> The basic approach here can be summarized as follows:
> - Define a new service: ActorResolverService responsible for interpreting the simple Actor name declared in the process. An instance implementing this interface is given to the TaskService as part of its configuration.
> - Modify the TaskService interface to add a method assignTaskToActors which accepts an Actor[] and recursively resolves all references to either a UserID or GroupID and creates tasks for each resolved entity.
> An alternative to modifying the TaskService would be to force each concrete Task to handle the resolution and assignment itself. I have initially rejected this approach because it seems out of the scope of concern of the task to handle this resolution, especially when the time comes to implement instance-level fields as actors (such as "self" or "initiator").
> Note that this patch removes the special actor "Self" from the Leave Application sample which is not yet implemented (and apparently not supported by the engine yet)
