STYLE: adjust comments and adjust surfaceMeshTriangulate code

Browse Source 
- note that it does not actually triangulate unless necessary, should
  probably receive a new name.

- use newer constructs for handling processor/non-processor patch
  selection etc.

Description
Extracts surface from a polyMesh. Depending on output surface format
triangulates faces.
Extract patch or faceZone surfaces from a polyMesh.
Depending on output surface format triangulates faces.
Region numbers on faces cannot be guaranteed to be the same as the patch
indices.
Region numbers on faces no guaranteed to be the same as the patch indices.
Optionally only triangulates named patches.
Optionally only extracts named patches.
If run in parallel the processor patches get filtered out by default and
the mesh gets merged (based on topology).

the mesh is merged (based on topology).
