STYLE: drop surface extraction from foamToStarMesh
- retain surfZone names when writing surfaces
- remove surface extraction/writing from meshWriter since it now
duplicates what the meshedSurface class can do.
- removed the previously added fileName type(), isDir(), isFile() methods.
- added optional bool parameter to isFile() function to explicitly
enable/disable the check for gzip files.
- fixed minor bugginess where the default usage of isFile() would result in
false positive matches.
- be slightly more stringent and use isDir() and isFile() instead of
exists() function when we actually know the expected type.
- renamed surface regions (formerly patches or groups) to surfZone.
- added surfMesh, but without any of the patch information needed to make it
useful for finiteArea.
- promoted coordinateSystem transformation to surfaceMeshConvert and moved
old to surfaceMeshConvertTesting.
- ditched PrimitivePatchExtra in favour of a PatchTools class that is
currently just a collection of static functions. They could equally well
live within PrimitivePatch itself, but isolated also has its advantages.
- MeshedSurface, UnsortedMeshedSurface now have 'regions' instead of
'patches' since they are more like a faceZone for meshed surfaces than
patches. This might avoid confusion at a later stage.
- expose faceMap info in triangulate() - for use in inherited classes
- surfMesh::triangulate() works with or without underlying pointField
- onePatch tries to be more intelligent about retaining the patch name
- 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
