+ * The process is a matter of filtering objectClasses up from
+ * unsorted into sorted. Order is irrelevent in the later 3 'bins'.
+ *
+ * We start with 'top' (found and promoted to parent_class
+ * initially). Then we find (in unsorted) all the direct
+ * subclasses of 'top'. parent_classes is concatenated onto
