AAA=faceZone to extrude.
For the case of no flipMap the extrusion starts at owner and extrudes
into the space of the neighbour:
+CCCCCCC+
| | <= extruded mesh
+BBBBBBB+
+-------------+
| |
| (neighbour) |
|___CCCCCCC___| <= original mesh (with 'baffles' added)
| BBBBBBB |
|(owner side) |

+-------------+
BBB=directMapped between owner on original mesh and new extrusion.
(zero offset)
CCC=directMapped between neighbour on original mesh and new extrusion
(offset due to the thickness of the extruded mesh)
For the case of flipMap the extrusion is the other way around: from the
neighbour side into the owner side.
