GIT: added missing source file.

ENH: add tutorial example under incompressible/simpleFoam/motorBike

- manifest in some parallel operations.

STYLE: update foamToEnsight, foamToEnsightParts to use C++ initializer_list

- avoid warning message when removing a non-existent directory (ensight output).

- Use ensightCase for case writing.
  Rebase ensightPartCells/ensightPartFaces on
  ensightCells/ensightFaces routines.

- Greatly reduces code duplication potential source of errors.

- Currently no writing of clouds.
  Managing restarts needs more thought.

- eliminate ensightAsciiStream, ensightBinaryStream, ensightStream in
  favour of using ensightFile and ensightGeoFile classes throughout.

- encapsulate mesh-parts sorting with the ensightCells, ensightFaces
  class.

- handle of patches/faceZones entirely within ensightMesh for a lighter
  interaction with field output. Both faceZones and point fields need
  more testing to see if they behave properly for all cases.

- move some output functionality into its own namespace
  'ensightOutput', move into a library.

- use the ensightCase class to open new ensight output streams
  in the proper sub-directory locations.

- part of generalizing the ensight infrastructure (issue #241)

- General bookkeeping when creating ensight files.

- intended as a base for various ensight-related handling

- Some commonly used write methods that are independent of
  the calling context (ie, 2D/3D data, geometry, fields)

- Provide singleton null() for ensightFile, ensightGeoFile.
  Can be used for MPI slaves that need a file reference for their
  methods, but will never write to it, but it is also reasonable
  to use an autoPtr with rawRef() for that as well.

- use explicit names within ensightPTraits

- In the foundation version they introduced a construct to handle
  the transition from 'wmRefresh' as an alias to 'wmRefresh' as
  a shell function. This transition is unnecessary for OpenFOAM+
  since 1606 used wmREFRESH (not wmRefresh) as an alias.

  For portability it is important to avoid this non-POSIX
  "type -t". It causes issues with dash and with zsh
  (mentioned in issue #277).

        type -t dash  ->   -t: not found
        type -t zsh   ->  zsh: bad option: -t

Note: zsh users may still noticed other problems.
For example, the POSIX 'unset -f' normally has no output, but in zsh
it reports an error and has exit code 1 if the function was not
previously defined. Whereas in POSIX (including bash, dash) it only
returns non-zero if the name(s) could not be unset.

Loop over the edges of each block rather than the edgeList of the
topological mesh due to problems with calcEdges for blocks with repeated
point labels

Merge branch 'merge-foundation' of develop.openfoam.com:Development/OpenFOAM-plus into merge-foundation

- A preliminary minor adjustment only.

ENH: Support more C++11 initializer lists (issue #261)

DynamicList
-----------
  - construction, assignment and append

HashSet
-------
  - construction, insert, set.
  - assignment will use the implicit List constructor

hashedWordList
--------------
  - construction, assignment
  - additional sort() and uniq() methods.
  - Readonly access to HashTable information via lookup() method.
  - NB: could avoid 'const char**' constructors in the future


Some tests are included

  - Write differences with respect to the specified dictionary
    (or sub entry if -entry specified)

  - Write the differences with respect to a template dictionary:
      foamDictionary 0/U -diff $FOAM_ETC/templates/closedVolume/0/U

  - Write the differences in boundaryField with respect to a
    template dictionary:
      foamDictionary 0/U -diff $FOAM_ETC/templates/closedVolume/0/U \
        -entry boundaryField
