/**
* 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
* @param string $scope The scopeField to select which tree to recover
* @return boolean true on success, false on failure
* @access public
* @link http://book.cakephp.org/view/1628/Recover
