    p: ProgressBar
) -> Result<(), Error>

Take a ManagedObject task, an mpsc tx, and a Progressbar. Execute task and regularly inform the rx (all the way over back in main())about our status using config::Worker.

TODO: allow the verbose bool to show the output of the tasks as they go.

Return () or io::Error (something went wrong in our task).
