/**
 * Provides a simple editor for adding jmri.jmrit.display items to a captive
 * JFrame.
 * <p>
 * GUI is structured as a band of common parameters across the top, then a
 * series of things you can add.
 * <p>
 * All created objects are put specific levels depending on their type (higher
 * levels are in front):
 * <ul>
 *   <li>BKG background
 *   <li>ICONS icons and other drawing symbols
 *   <li>LABELS text labels
 *   <li>TURNOUTS turnouts and other variable track items
 *   <li>SENSORS sensors and other independently modified objects
 * </ul>
 * <p>
 * The "contents" List keeps track of all the objects added to the target frame
 * for later manipulation.
 * <p>
 * If you close the Editor window, the target is left alone and the editor
 * window is just hidden, not disposed. If you close the target, the editor and
 * target are removed, and dispose is run. To make this logic work, the
 * PanelEditor is descended from a JFrame, not a JPanel. That way it can control
 * its own visibility.
 * <p>
 * The title of the target and the editor panel are kept consistent via the
 * {#setTitle} method.
