+ *
+ * @uses global $wp_meta_boxes Used to retrieve registered meta boxes.
+ *
+ * @param string|object $screen The screen identifier.
+ * @param string $context The meta box context.
+ * @param mixed $object gets passed to the section callback function as first parameter.
+ * @return int number of meta boxes as accordion sections.
