 sets of IS's that define a coloring of the underlying indices

Synopsis

struct _p_ISColoring {
  int            refct;
  int            n;                /* number of colors */
  IS             *is;              /* for each color indicates columns */
  MPI_Comm       comm;
  int            *colors;          /* for each column indicates color */
  int            N;                /* number of columns */
  ISColoringType ctype;
};

Notes

One should not access the *is records below directly because they may not yet have been created. One should use ISColoringGetIS() to make sure they are created when needed.
