- only occurs in combination with distributedTriSurfaceMesh in snappy.

- workaround similar to that previously used for surfaceRedistributePar
  (issue #60).

Minor adjustment of incompressible motorBike tutorial to detect use of
distributedTriSurfaceMesh.

- 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

The best of the current options is to use the latest version of
exuberant ctags (which has a new C++ parser) to generate both
declaration and definition tags.

gtags works to some extent and provides additional information about the
function signatures but the C++ parser is not accurate and misses scope
information.  gtags can be used with the ctags parser which is effective
but looses the primary advantage of gtags being able to provide function
signatures so support has been switched-off by default.

ebrowse does not appear to be very useful for traversing the OpenFOAM
class tree and the support has been switched-off by default.

ctags-exuberant is now the more common name for the exuberant ctags
program.

Commented-out gtags as it is not commonly available.

- include cleanup of other postProcessing directories:
  * Ensight, EnSight, ensightWrite

- don't need to remove files that cleanSnappyFiles already removed:
  * 0/cellLevel 0/pointLevel

- bundle removal of constant/ items together:
  * constant/cellDecomposition constant/polyMesh constant/tetDualMesh

- Can occur with some user names, or mounted paths.
  Resolve by using '?' for the separation character.

  Since '?' is a shell-glob, it is highly unlikely to occur appear in
  filenames.  Additionally, it is not a meta-character in standard sed,
  nor in the GNU extension (which uses '\?').

- allows writing Allrun scripts that can be easily tested in
  serial or parallel

   1. Spaced ending of multi-level template parameters are not allowed, such as:

       List<List<scalar> >

     which instead should be:

       List<List<scalar>>

   2. The use of the 'NULL' macro should be replaced by 'nullptr'

Provides efficient integration of complex laminar reaction chemistry,
combining the advantages of automatic dynamic specie and reaction
reduction with ISAT (in situ adaptive tabulation).  The advantages grow
as the complexity of the chemistry increases.

Two tutorial cases are currently provided:
    + tutorials/combustion/chemFoam/ic8h18_TDAC
    + tutorials/combustion/reactingFoam/laminar/counterFlowFlame2D_GRI_TDAC

the first of which clearly demonstrates the advantage of dynamic
adaptive chemistry providing ~10x speedup,

the second demonstrates ISAT on the modest complex GRI mechanisms for
methane combustion, providing a speedup of ~4x.

More tutorials demonstrating TDAC on more complex mechanisms and cases
will be provided soon in addition to documentation for the operation and
settings of TDAC.  Also further updates to the TDAC code to improve
consistency and integration with the rest of OpenFOAM and further
optimize operation can be expected.

Implementation updated, optimized and integrated into OpenFOAM-dev by
Henry G. Weller, CFD Direct Ltd with the help of Francesco Contino.

- remove old VTK_CONVEX_POINT_SET code, since VTK_POLYHEDRON exists
  since several years

ENH: improve robustness of paraFoam script

- only check the relevant plugin types,
  fallback to native reader if needed/possible.

- no engrid development since 2013

- remove duplicate 0/ files from the repository

- makes it easier to ensure the correct behaviour, consistently

postProcess -func writeCellCentres

Added a 'deprecated' comment and recommendation to use 'foamLog'

dictionary files of a particular name and extracts entries of a
particular keyword, sorting results into a unique list.

For example,
    foamSearch $FOAM_TUTORIALS laplacianSchemes.default fvSchemes

produces...
    default         Gauss linear corrected;
    default         Gauss linear limited corrected 0.33;
    default         Gauss linear limited corrected 0.5;
    default         Gauss linear orthogonal;
    default         Gauss linear uncorrected;
    default         none;

Uses the fantastic foamDictionary utility.

    postProcess -func 'totalPressureIncompressible(U,p)'
or
    postProcess -func 'totalPressureCompressible(rho,U,p)'

To re-use existing 'sampleDict' files simply add the following entries:

    type sets;
    libs ("libsampling.so");

and run

    postProcess -func sampleDict

It is probably better to also rename 'sampleDict' -> 'sample' and then run

    postProcess -func sampleDict

e.g.
    postProcess -func 'patchAverage(name=inlet,p)'
    postProcess -func 'patchIntegrate(name=inlet,p)'
