Class
    Foam::fieldAverageItem

Description
    Helper class to describe what form of averaging to apply. A set will be
    applied to each base field in Foam::fieldAverage, of the form:

    \verbatim
        {
            mean            on;
            prime2Mean      on;
            base            time; // iteration
        }
    \endverbatim
