Class
    Foam::functionObjects::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;   // (default = on)
        prime2Mean      on;   // (default = off)
    }
    \endverbatim
