changed faceZone flip map usage

@@ -28,8 +28,8 @@ Description
 
     There is one catch: for faceZones you also need to specify a flip
     condition which basically denotes the side of the face. In this app
-    it reads a cellSet (xxxCells if 'xxx' is the name of the faceSet) and
-    any face whose neighbour is in the cellSet gets a flip=true.
+    it reads a cellSet (xxxCells if 'xxx' is the name of the faceSet) which
+    is the masterCells of the zone.
     There are lots of situations in which this will go wrong but it is the
     best I can think of for now.
