   show_menu

 From: http://forum.websitebaker.org/index.php/topic,2251.msg13978.html#msg13978

 * By calling it multiple times, you can have one menu just

 * showing the root level, one for the sub-pages, and so on

 * The order of the arguments has been changed compared

 * to the page_menu() function, so read carefully the list

 * of arguments!

 * To just display the standard menu, use

 * <?php show_menu(); ?> within your template's html code.

 * You don't normally need anymore than the first four arguments.

 * Usual calls would be (inside php code!)

 * show_menu(1,0,-1,false); - displays the complete page tree

 * show_menu(1,1,1); - show only first sub level

 * show_menu(1,1,-1); -    show an expanding/collapsing menu tree starting at level 1

 * Have fun experimenting!

 *

 * Full list of arguments:

 * 1. $menu_number:   With activitated "multiple menu" feature

 *                  you can choose which menu will be displayed

 *                  default: 1

 * 2. $start_level: The depth level of the root of the displayed

 *               menu tree. Defaults to '0', which is the top level.

 *                  '1' will show all pages starting from the first sub level.

 * 3. $recurse:     Gives the maximum number of levels to be displayed. Default

 *                  is '-1' which means 'all'.

 * 4. $collapse:    Specifies, whether the menu tree shall be

 *               expandable/collapsible (if set to 'true')

 *               or complete (all pages being displayed) if set to 'false'

 * 5. $item_template: Gives the possibility to specify the html code that is

 *                  displayed before displaying sub-pages

 * 6. $item_footer: The html code to appear after sub-pages were displayed.

 * 7. $menu_header: The html code to appear before the entire menu code and each

 *               sub tree.

 * 8. $menu_footer: The html code to appear after the entire menu code and each

 *               sub tree.

 * 9. $default_class: The (CSS) class of every menu item except the currently viewed page

 * 10. $current_class: The class of the currently viewed page

 * 11. $parent:    (used internally) The page_id of the menu's root node, defaults is '0' (root level)
