 *                            validate the records, but not save them.
 *                          - atomic: If true (default), will attempt to save all records in a single transaction.
 *                            Should be set to false if database/table does not support transactions.
 *                              If false, we return an array similar to the $data array passed, but values are set to true/false
 *                              depending on whether each record saved successfully.
 *                          - fieldList: Equivalent to the $fieldList parameter in Model::save()
 * @return mixed True on success, or false on failure
