Initialize faceAgglom list to identity when a patch is not agglomerated in faceAgglomerate.C
Restrict agglomeration through edges with more than two faces attached in pairPatchAgglomeration.C
Modification of shootRays algorithm. Rays that hit themselfs are continued
until they hit(or not) the agglomeration target. If they do the surfaces can see
each other.
faceAgglomerate:
The agglomeration now stops when the global nCoarse is reached (not per-processor)
