/**
 * Dialog wrapper of a command visualizer.

 * This dialog is to be used when it is necessary to wait for a command task
 * in AWT thread. This dialog is able to wrap any GUI that can be presented
 * by the command so that it will not collide with the blocked AWT event queue.
 * 

 * This dialog is modal, therefore its presentation is blocking, but another
 * event pump is started so that the system stays responsive.
