+Description
+    Extrudes by rotating a surface around an axis
+    - extrusion is opposite the surface/patch normal so inwards the source
+      mesh
+    - axis direction has to be consistent with this.
+    - use -mergeFaces option if doing full 360 and want to merge front and back
+    - note direction of axis. This should be consistent with rotating against
+      the patch normal direction. If you get it wrong you'll see all cells
+      with extreme aspect ratio and internal faces wrong way around in
+      checkMesh
