using nested ProgressTask

[Michael Gliwinski]

Hello All,

Not sure what I'm doing wrong but when I create a nested progress bar 
(ProgressTask) like:

  ...
  def run(self, ...):
      pb = ui.ui_factory.nested_progress_bar()
      ...
      func(..., pb=pb)

  def func(..., pb)
      spb = pb.make_sub_task()
      ...
      spb.finished()

I'm getting a "UserWarning ProgressTask(...) is not in active stack" on that 
call to spb.finished()

AFAICS this is because ProgressTask.make_sub_task does not add the subtask to 
UIFactory's _task_stack.

Is this a bug or am I not using it the way it was intended?

Thanks,
Michael
