   This defines two structures:

   datamat is the data matrix, with some ancillary data structures

   nrows, ncols      number of rows and columns
   rowlabs, collabs  arrays of character strings with labels
   data              double array of original data values
   blkind            double array of indicators, showing which elements
                        have a block value
   colvals           an array of categval holding all of column values

   categval    This lists the unique column values for each column
       nvals   The number of unique values
       vals    Array of unique values
