Foam::hexCellLooper

Description
28
Implementation of cellLooper.
29
30
This one walks hexes in a topological way:
31
- cross edge to other face
32
- cross face by walking edge-point-edge across to reach the other side.
33
(edges are always cut through the middle)
34
35
For anything else (tet, prism, .. poly) it will use geomCellLooper
36
(which does a purely geometric cut using a plane through cell centre)
