/**
* Placeholder. Output multigrouped
*
* A means of putting mptt data in a select box (using groups?) is needed. Must still be possible to select
* (intermediary) parents.
* A convenience method for returning a hierarchical array used for HTML select boxes
*
* @param AppModel $model
* @param mixed $conditions SQL conditions as a string or as an array('field' =>'value',...)
* @param string $order SQL ORDER BY conditions (e.g. "price DESC" or "name ASC")
* @param int $limit SQL LIMIT clause, for calculating items per page
* @param string $keyPath A string path to the key, i.e. "{n}.Post.id"
* @param string $valuePath A string path to the value, i.e. "{n}.Post.title"
* @param string $groupPath A string path to a value to group the elements by, i.e. "{n}.Post.category_id"
* @param string $spacer The character or characters which will be repeated
* @param int $recursive The number of levels deep to fetch associated records
* @return array An associative array of records, where the id is the key, and the display field is the value
* @access public
