in decomposeParDict.

This default number of processors may be overridden by the new "-np"
option to runParallel which must be specified before the application
name e.g.:

runParallel -np 4 pisoFoam

which may be optionally overridden by version-specific rules.

For example the default rules for gcc on GNU/Linux x86_64 are in the
wmake/rules/linux64Gcc directory.  If there is a need to change any of
the rules for a specific version of gcc, e.g. gcc-4.8.4 the directory
wmake/rules/linux64Gcc48 may be created into which any of the language
files may be provided containing the rules to override the defaults.

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.
