28 * Generating navigation / menus from TypoScript
29 *
30 * This file contains five classes, four of which are extensions to the main class, tslib_menu.
31 * The main class, tslib_menu, is also extended by other external PHP scripts such as the GMENU_LAYERS and GMENU_FOLDOUT scripts which creates pop-up menus.
32 * Notice that extension classes (like "tslib_tmenu") must have their suffix (here "tmenu") listed in $this->tmpl->menuclasses - otherwise they cannot be instantiated.

58 * Base class. The HMENU content object uses this (or more precisely one of the extension classes).
59 * Amoung others the class generates an array of menuitems. Thereafter functions from the subclasses are called.
60 * The class is ALWAYS used through extension classes (like tslib_gmenu or tslib_tmenu which are classics) and
61 *
62 * Example of usage (from tslib_cObj):
63 *
64 * $menu = t3lib_div::makeInstance('tslib_'.$cls);
65 * $menu->parent_cObj = $this;
66 * $menu->start($GLOBALS['TSFE']->tmpl,$GLOBALS['TSFE']->sys_page,'',$conf,1);
