     A `groupedData' object is at least a data.frame and a display 
     formula that provides a grouping structure.  In the
     `nmGroupedData' class there are multiple level of grouping factors
     and the response in the display formula is numeric.  At present we
     use old-style classes for `groupedData' and the classes that
     inherit from it.
