 /**
  * Recover a corrupted tree
  *
  * The mode parameter is used to specify the source of info that is valid/correct. The opposite source of data
  * will be populated based upon that source of info. E.g. if the MPTT fields are corrupt or empty, with the $mode
  * 'parent' the values of the parent_id field will be used to populate the left and right fields. The missingParentAction
  * parameter only applies to "parent" mode and determines what to do if the parent field contains an id that is not present.
  *
  * @todo Could be written to be faster, *maybe*. Ideally using a subquery and putting all the logic burden on the DB.
  * @param AppModel $Model Model instance
  * @param string $mode parent or tree
  * @param mixed $missingParentAction 'return' to do nothing and return, 'delete' to
  * delete, or the id of the parent to set as the parent_id
  * @return boolean true on success, false on failure
  * @access public
  * @link http://book.cakephp.org/view/1628/Recover
