- added protected storedPoints(), storedFaces() functions for non-const
access to the data. Mixing protected non-const versions and public const
versions of the same method does not agree with the compiler
- better handling of triFace/face distinction
- keyedSurface is similar to triSurface, but uses faces
- meshedSurface is sorted in regions and should be more memory efficient
- surfMesh is the placeholder name for an OpenFOAM native surface format
