  - There will be triangles rendered inside the mesh (when
    surface-rendering), because one of the cell's triangles is defined
    as a quadrangle in VTK_WEDGE.

  - Therefore, this VTK_WEDGE representation is only used when
    decomposing the mesh, otherwise the correct representation is done
    by VTK_POLYHEDRON.

  - Furthermore, using VTK_PYRAMID gave worse result, because it renders
    2 triangles inside the mesh for the collapsed quadrangle, likely due
    to mismatch with the adjacent cell's face.

  - Using VTK_HEXAHEDRON was not tested in this iteration, given that it
    should give even worse results, when compared to using VTK_PYRAMID.

SLList: now a C++11 template alias rather than a wrapper-class.

Now the functionality to write single graph files or log files (vs time)
may be used in the creation of any form of functionObject, not just
those relating to a mesh region.

e.g.
    HashTable<label, string> table1
    {
        {"kjhk", 10},
        {"kjhk2", 12}
    };

    HashTable<label, label, Hash<label>> table2
    {
        {3, 10},
        {5, 12},
        {7, 16}
    };

Requires gcc version 4.7 or higher

FixedList: Add constructors from iterators and C++11 initializer_list using C++11 constructor delegation

Test-List: Add demonstration of C++11 initializer list in conjunction with uniform initialization of vector

     List<vector> list5
     {
         {5, 3, 1},
         {10, 2, 2},
         {8, 1, 0}
     };

Until C++ supports 'concepts' the only way to support construction from
two iterators is to provide a constructor of the form:

        template<class InputIterator>
        List(InputIterator first, InputIterator last);

which for some types conflicts with

        //- Construct with given size and value for all elements
        List(const label, const T&);

e.g. to construct a list of 5 scalars initialized to 0:

    List<scalar> sl(5, 0);

causes a conflict because the initialization type is 'int' rather than
'scalar'.  This conflict may be resolved by specifying the type of the
initialization value:

    List<scalar> sl(5, scalar(0));

The new initializer list contructor provides a convenient and efficient alternative
to using 'IStringStream' to provide an initial list of values:

    List<vector> list4(IStringStream("((0 1 2) (3 4 5) (6 7 8))")());

or

    List<vector> list4
    {
        vector(0, 1, 2),
        vector(3, 4, 5),
        vector(6, 7, 8)
    };

Thanks to Bruno Santos for providing the script to check the files

TurbulenceModels: Reorganized support macros to simplify the creation of additional turbulence model libraries

  - the checking for point-connected multiple-regions now also writes the
    conflicting points to a pointSet
  - with the -writeSets option it now also reconstructs & writes pointSets

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.
