/**
 *  Implementation of  PreferencesFactory to return PreferencesExt objects. Using this
 *  method of obtaining a Preferences object is optional; you can also just pass around the
 *  Preferences object explicitly.
 *
 *  The default Preferences.userRoot() and Preferences.systemRoot() are empty. To use
 *  persistent versions, you must set them explicitly through
 *   *    PreferencesExt.setSystemRoot( PreferencesExt prefs);
 *    PreferencesExt.setUserRoot( PreferencesExt prefs);
 *  
 *  and also call:
 *   *    System.setProperty("java.util.prefs.PreferencesFactory", "ucar.util.prefs.PreferencesExtFactory");
 *
