 Description
     Neighbour processor patch.
 
-    Note: morph patch face ordering comes geometric or topological.
-    Geometric: no cyclics allowed (assumes faces coincident)
-    Topological: needs unmodified faces on both sides to correspond. Also
-    needs at least one per connected patch area (so all patch faces can be
-    visited from an unmodified face)
+    Note: morph patch face ordering tries to do a geometric ordering.
+    (assumes faces coincident) Hence will have problems when cyclics
+    are present.
