The number of characters needed to print a double in scientific format
is 8 plus the number of decimal places; e.g., -6.453452e-231 (6 decimal
places, 14 characters). This has been set in writeFile.C, replacing a
value of 7. Presumably, the case of three digits in the exponent was not
considered when this was first implemented. This change ensures at least
one character of whitespace between tabulated numbers.

Thermo and reaction thermo macros have been renamed and refactored. If
the name is plural (make???Thermos) then it adds the model to all
selection tables. If not (make???Thermo) then it only adds to the
requested psi or rho table.

This mixture allows a reacting solver to be used with a single component
fluid without the additional case files usually required for reacting
thermodynamics.

reactionThermo: Instantiated more single component mixtures

ENH: reactionThermo: Select singleComponentMixture as pureMixture

A pureMixture can now be specified in a reacting solver. This further
enhances compatibility between non-reacting and reacting solvers.

To achieve this, mixtures now have a typeName function of the same form
as the lower thermodyanmic models. In addition, to avoid name clashes,
the reacting thermo make macros have been split into those that create
entries on multiple selection tables, and those that just add to the
reaction thermo table.

The combustion and chemistry models no longer select and own the
thermodynamic model; they hold a reference instead. The construction of
the combustion and chemistry models has been changed to require a
reference to the thermodyanmics, rather than the mesh and a phase name.

At the solver-level the thermo, turbulence and combustion models are now
selected in sequence. The cyclic dependency between the three models has
been resolved, and the raw-pointer based post-construction step for the
combustion model has been removed.

The old solver-level construction sequence (typically in createFields.H)
was as follows:

    autoPtr<combustionModels::psiCombustionModel> combustion
    (
        combustionModels::psiCombustionModel::New(mesh)
    );

    psiReactionThermo& thermo = combustion->thermo();

    // Create rho, U, phi, etc...

    autoPtr<compressible::turbulenceModel> turbulence
    (
        compressible::turbulenceModel::New(rho, U, phi, thermo)
    );

    combustion->setTurbulence(*turbulence);

The new sequence is:

    autoPtr<psiReactionThermo> thermo(psiReactionThermo::New(mesh));

    // Create rho, U, phi, etc...

    autoPtr<compressible::turbulenceModel> turbulence
    (
        compressible::turbulenceModel::New(rho, U, phi, *thermo)
    );

    autoPtr<combustionModels::psiCombustionModel> combustion
    (
        combustionModels::psiCombustionModel::New(*thermo, *turbulence)
    );

ENH: combustionModel, chemistryModel: Simplified model selection

The combustion and chemistry model selection has been simplified so
that the user does not have to specify the form of the thermodynamics.

Examples of new combustion and chemistry entries are as follows:

    In constant/combustionProperties:

        combustionModel PaSR;

        combustionModel FSD;

    In constant/chemistryProperties:

        chemistryType
        {
            solver          ode;
            method          TDAC;
        }

All the angle bracket parts of the model names (e.g.,
<psiThermoCombustion,gasHThermoPhysics>) have been removed as well as
the chemistryThermo entry.

The changes are mostly backward compatible. Only support for the
angle bracket form of chemistry solver names has been removed. Warnings
will print if some of the old entries are used, as the parts relating to
thermodynamics are now ignored.

ENH: combustionModel, chemistryModel: Simplified model selection

Updated all tutorials to the new format

STYLE: combustionModel: Namespace changes

Wrapped combustion model make macros in the Foam namespace and removed
combustion model namespace from the base classes. This fixes a namespace
specialisation bug in gcc 4.8. It is also somewhat less verbose in the
solvers.

This resolves bug report https://bugs.openfoam.org/view.php?id=2787

ENH: combustionModels: Default to the "none" model

When the constant/combustionProperties dictionary is missing, the solver
will now default to the "none" model. This is consistent with how
radiation models are selected.

ENH: compressibleInterFoam family: merged two-phase momentum stress modelling from compressibleInterPhaseTransportFoam

The new momentum stress model selector class
compressibleInterPhaseTransportModel is now used to select between the options:

Description
    Transport model selection class for the compressibleInterFoam family of
    solvers.

    By default the standard mixture transport modelling approach is used in
    which a single momentum stress model (laminar, non-Newtonian, LES or RAS) is
    constructed for the mixture.  However if the \c simulationType in
    constant/turbulenceProperties is set to \c twoPhaseTransport the alternative
    Euler-Euler two-phase transport modelling approach is used in which separate
    stress models (laminar, non-Newtonian, LES or RAS) are instantiated for each
    of the two phases allowing for different modeling for the phases.

Mixture and two-phase momentum stress modelling is now supported in
compressibleInterFoam, compressibleInterDyMFoam and compressibleInterFilmFoam.
The prototype compressibleInterPhaseTransportFoam solver is no longer needed and
has been removed.

Another exception has been added to globalIndexAndTransform to prevent
transformations being generated from coupled patch pairs marked with
coincident-full-match transformations. Foamy generates such patches, and
the faces on them at intermediate stages of meshing can be degenerate,
making the calculation of transformations unreliable. This change
enforces the definition that coincident-full-match patch pairs are not
transformed.
