/**
 * The renderer that creates an array of visible menu entries.

 * The resultant array can be used with e.g. a template engine to produce
 * a completely custom menu look.
 * All menu types except 'rows' are "rendered" into a one-dimensional array
 * of entries:
 * <pre>
 * array(
 *    'entry1',
 *    ...
 *    'entryN'
 * )
 * </pre>
 * while 'rows' produce a two-dimensional array:
 * <pre>
 * array(
 *    array('entry 1 for row 1', ..., 'entry M_1 for row 1'),
 *    ...
 *    array('entry 1 for row N', ..., 'entry M_N for row 1')
 * )
 * </pre>
 * Here entry is
 * <pre> 
 * array(
 *    'url'    => url element of menu entry
 *    'title'  => title element of menu entry
 *    'level'  => entry's depth in the tree structure
 *    'type'   => type of entry, one of HTML_MENU_ENTRY_* constants
 *    // if the nodes in the original menu array contained keys other
 *    // than 'url', 'title' and 'sub', they will be copied here, too
 * )
