     A `groupedData' object is at least a data.frame and a display 
     formula that provides a grouping structure.  In the
     `nfGroupedData' class there is only one level of grouping factors
     and the response in the display formula is numeric.  The
     `nfnGroupedData' class is a further refinement that specifies that
     the primary covariate is numeric. At present we are using
     old-style classes for `groupedData' and the classes that extend
     it.
