 * This class provides a bookmark menu.  It is typically used in
 * cooperation with KActionMenu but doesn't have to be.
 *
 * If you use this class by itself, then it will use KDE defaults for
 * everything -- the bookmark path, bookmark editor, bookmark launcher..
 * everything.  These defaults reside in the classes
 * KBookmarkOwner (editing bookmarks) and KBookmarkManager
 * (almost everything else).  If you wish to change the defaults in
 * any way, you must reimplement either this class or KBookmarkOwner.
 *
 * Using this class is very simple:
 *
 * 1) Create a popup menu (either KActionMenu or KMenu will do)
 * 2) Instantiate a new KBookmarkMenu object using the above popup
 *    menu as a parameter
 * 3) Insert your (now full) popup menu wherever you wish
