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

construction of the phases is not complete
