Also removed __GNUC__ conditional compilation statements which are no
longer needed.

The interfacial temperature is assumed equal to the saturation
temperature.  Only a single species is considered volatile and the other
species to not affect the mass-transfer.

Added calls to setFluxRequired for p, p_rgh etc. in all solvers which
avoids the need to add fluxRequired entries in fvSchemes dictionaries.

Added calls to setFluxRequired for p in all incompressible solvers which
avoids the need to add fluxRequired entries in fvSchemes dictionary.

Will add calls to setFluxRequired to the rest of the solvers.

cellCoBlended: New surfaceInterpolation scheme based on CoBlended using the cell-based Courant number

    This scheme is equivalent to the CoBlended scheme except that the Courant
    number is evaluated for cells using the same approach as use in the
    finite-volume solvers and then interpolated to the faces rather than being
    estimated directly at the faces based on the flux.  This is a more
    consistent method for evaluating the Courant number but suffers from the
    need to interpolate which introduces a degree of freedom.  However, the
    interpolation scheme for "Co" is run-time selected and may be specified in
    "interpolationSchemes" and "localMax" might be most appropriate.

    Example of the cellCoBlended scheme specification using LUST for Courant
    numbers less than 1 and linearUpwind for Courant numbers greater than 10:
    \verbatim
    divSchemes
    {
        .
        .
        div(phi,U)  Gauss cellCoBlended 1 LUST grad(U) 10 linearUpwind grad(U);
        .
        .
    }

    interpolationSchemes
    {
        .
        .
        interpolate(Co) localMax;
        .
        .
    }
    \endverbatim

The standard merge-algorithm is N^2 over the face-points and uses a
geometric proximity test for the merge.  These are both choices for
implementation simplicity and are rather inefficient for large meshes.
I have now implemented an experimental linear topological merge
algorithm which is VERY fast and effective for meshes of any size.
Currently it will merge internal faces on meshes of arbitrary complexity
but does not yet handle edge or face collapse needed for wedges and
other degenerate blocks.

The new fast-merge algorithm may be selected using the optional
"fastMerge" entry:

fastMerge yes;

and if not present the standard N^2 algorithm will be used.

Currently this is implemented only for the Antoine equation, for the
other more complex models an iterative inversion from pressure to
temperature is required.

posPart returns a value or field in which the value or values are set to
0 if negative

negPart returns a value or field in which the value or values are set to
0 if positive

In preparation for adding the Tsat function

for consistency with the evaluation of the interface temperature.

Needs rewriting to avoid unnecessary code duplication, preferably using
standard OpenFOAM interpolation functionality.

Generally this term has a VERY small effect on temperature, it is only
important for low-speed buoyancy-dominated flows.

patchMeanVelocityForce: Variant of patchMeanVelocityForce in which the velocity is averaged over a patch
rather than a cellSet

This is useful to drive mean flow in a duct with a non-uniform
cross-section.

as it is the applied the force necessary to maintain the specified mean velocity
