[Anthill-pro] Is there an example of the Manual Workflow Choice Task?

[Heather Wells]

The manual workflow choice task is briefly mentioned in the manual,  
and I've created a job with a workflow choice task, but now I'm  
stumped.  I run the process containing this task, and I don't see  
where the user is presented with the choice of which workflow to run.   
I would love to see an example of this kind of task in use.
