reactionThermo/functionObjects/moleFractions/moleFractions: New functionObject to calculate and write mole-fraction fields

    This function object calculates mole-fraction fields from the mass-fraction
    fields of the psi/rhoReactionThermo and caches them for output and further
    post-processing.

    The names of the mole-fraction fields are obtained from the corresponding
    mass-fraction fields prepended by "X_"

    Example of function object specification:

        moleFractions
        {
            type psiReactionThermoMoleFractions;
        }

     or

        moleFractions
        {
            type rhoReactionThermoMoleFractions;
        }

    depending on the thermodynamics package used in the solver.

temperatureDependentAlphaContactAngleFvPatchScalarField: Temperature-dependent constant alphaContactAngle scalar boundary condition

Evaluates the contact angle as a function of the optionally specified
temperature field (defaults to T).  The "theta0" function is provided as
a DataEntry currently supporting:
    CompatibilityConstant
    constant
    csvFile
    polynomial
    table
    tableFile

for consistency with prghPressureFvPatchScalarField

Corrected rho name specification.

It is not clear what form an fvOptions source should take as f is not a
transported dynamic field. For the moment the fvOptions source from the
f-equation has been removed until there is a specific need which will
show what the form should be.

Starting from an initial buffer size of 256 it is incremented in steps
of 256 upto the maximum of 4096 as required.

declaring the namespace in function definitions in C files

Requires that metis is compiled with REALTYPEWIDTH set to 32 for SP and 64 for DP.

It is better to declare the namespace of each function in the C file
rather than "open" the namespace as this may lead to inconsistencies
between the declaration in the H files and definition in the C file.
