/**
 * The main window of the Joty application.
 * 
 * On exiting it is responsible, with the {@code Application} class, to ask each
 * application window to close.
 * 

 * It can assume two states: the normal one, as the application starts and as
 * background of communications to the user at the application level, and second
 * one consisting in a reduced floating and always on top form that encloses
 * just the application menu.
 * 
 * The class provides methods to switch to and from the reduced form and the
 * framework invokes them to reduce the JotyFrame instance at every opening of a
 * {@code DataAccessDialog} object.
 *
 * @see Application
 * @see DataAccessDialog
