* preventing access to it while still being slighly visible.
* This class also features a progressbar to indicate progress of the busyness.
*
* BusyOverlay is meant to be as unintrusive as possible. One simply constructs
* it with the base and sets up a suitable connection for setProgress and throwAway.
* Everything else is handled by the overlay automatically. It will also take
* care of deleting itself again.
