/**
 * Provides a simple editor for adding jmri.jmrit.display.switchBoard items to a
 * JLayeredPane inside a captive JFrame. Primary use is for new users.
 * <p>
 * GUI is structured as a separate setup panel to set the visible range and type
 * plus menus.
 * <p>
 * All created objects are placed in a GridLayout grid. No special use of the
 * LayeredPane layers. Inspired by Oracle JLayeredPane demo.
 * <p>
 * The "switchesOnBoard" LinkedHashMap keeps track of all the objects added to the target
 * frame for later manipulation. May be used in an update to store mixed
 * switchboards with more than 1 connection and more than 1 bean type/range.<br>
 * The 'ready' flag protects the map during regeneration.
 * <p>
 * No DnD as panels will be automatically populated in order of the DCC address.
 * New beans may be created from the Switchboard by right clicking an
 * unconnected switch.
 * TODO allow user entry of connection specific starting name, validated in manager
 * using hardwareAddressValidator
