Class
    Foam::moleFractions

Description
    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:
    \verbatim
    moleFractions
    {
        type psiReactionThermoMoleFractions;
    }
    \endverbatim
    or
    \verbatim
    moleFractions
    {
        type rhoReactionThermoMoleFractions;
    }
    \endverbatim
    depending on the thermodynamics package used in the solver.
