Note: classes are prefixed with 'foamVtk' instead of 'vtk' to avoid potential
conflicts with VTK itself.

foamVtkCore
~~~~~~~~~~~
- General very low-level functionality.

foamVtkPTraits
~~~~~~~~~~~~~~
- Traits type of functionality for VTK

foamVtkOutputOptions
~~~~~~~~~~~~~~~~~~~~
- The various format output options as a class that can be passed to
  formatters etc.

foamVtkCells
~~~~~~~~~~~~
- Intended for unifying vtkTopo and PV-Reader code in the future.
- Handles polyhedron decompose internally etc

foamVtkOutput, foamVtkFormatter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Output helpers.
- Selector for individual formatters.
  Currently write all scalar data a 'float' (not 'double'). Can
  revisit this in the future.

- Reduce code duplication by moving out common functionality
  into STARCDCore.

- reuse for foamToTecplot360 and foamToVTK.
- remove dependency on vtkMesh where possible.

Feature keep sampled pids

Rebased version of merge request !58, following ticket closure for issue #104 .

See merge request !75

- relied on 'export' keyword, which was removed in commit b8448671

ENH: foamConfigurePaths support for additional items:

    -label 32|64            specify label size
    -system name            specify 'system' compiler to be used
    -thirdParty name        specify 'ThirdParty' compiler to be used

    -boost ver              specify boost_version
    -boostArchPath dir      specify BOOST_ARCH_PATH
    -cgal ver               specify cgal_version
    -cgalArchPath dir       specify CGAL_ARCH_PATH
    -clang ver              specify clang_version for ThirdParty Clang
    -cmake ver              specify cmake_version
    -fftw ver               specify fffw_version
    -fftwArchPath dir       specify FFTW_ARCH_PATH
    -metis ver              specify METIS_VERSION
    -metisArchPath dir      specify METIS_ARCH_PATH

- Follow similar pattern as per boost/CGAL with the '*-none' to disable,
  and '*-system' for system installations.

  Also support central non-ThirdParty installations by specifying the
  version as "*-system", but also providing the fully qualified
  *_ARCH_PATH too.

ENH: Verify label and scalar sizes used in the metis header.

- ensure they match with expected values, which can be obtained via
  the OpenFOAM definitions for WM_LABEL_SIZE and WM_PRECISION_OPTION

- Only reference the FOAM_EXT_LIBBIN locations when linking.
  The respective SCOTCH_ARCH_PATH/lib, METIS_ARCH_PATH/lib locations
  either do not exist, or are possibly inconsistent and won't be
  seen at run-time anyhow.

- Incorporate decompose/metisDecomp/Allwmake into the top-level
  decompose/Allwmake

On 64-bit systems, the system installations of boost, cgal are under
lib64/. The behaviour for a ThirdParty build is mostly lib/ but this
can also be changing.

    Boost 1_62_0 and older build into 'lib/'.
    CGAL-4.9 builds into 'lib64/', older versions into 'lib/'.

Future-proof things by using lib$WM_COMPILER_LIB_ARCH for boost and
cgal build rules, and forcing these as build targets in the ThirdParty
makeCGAL as well.

--
STYLE: check for boost/version.hpp, CGAL/version.h instead their directories

- was incorrectly writing it as "startFace", which would be
  immediately overwritten anyhow

STYLE: avoid noisy output when adding the boundary 'type' in mesh conversion.

Reworking of the ensight infrastructue and new ensightWrite function object



See merge request !70

Provide common face area/normal support in PrimitivePatch

For polyPatch, both the faceAreas() and faceCentres() are masked by their subField equivalents.
Since there is no polyPatch method for magFaceAreas(), the PrimitivePatch method will be seen.

See merge request !74

- still needs to be applied and tested
