A desktop on which to place internal frames displaying Probe data.
There are some subtleties here that arise from the way Swing is implemented. All Swing GUI events are processed on the "Swing event thread," and that includes all methods of this object. This should be obvious for most methods since they are called from GUI components such as Buttons.
The basic protocol of this module is simple. When a new Probe is requested by a user command (such as a button click), the ProbeDesktop creates a ProbeFrame where that Probe can be viewed.
