/**
* 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
* )
* </pre>
