       Bivar currently supports two parameters. The current values may be retrieved using one of the routines
       IDGETI or IDGETR. Parameter values may be reset using the routine IDSETI or IDSETR.

       The Bivar parameter descriptions appear below in alphabetical order. Each description begins with a line
       giving the parameter name and the intrinsic FORTRAN type of the parameter.

       'ITY' - Integer
              Interpolation  Type.   The  default value, 0, says that quintic interpolation should be done.  The
              value 1 says to use linear interpolation.

       'TTY' - Integer
              Triangulation Type.  The default value, 0, says to use a triangulation due to C.  L.  Lawson  that
              maximizes  the  minimum  angle  occurring  in the triangles.  The value 1 says to use the Delaunay
              triangulation, which ensures triangles whose circumscribed circles have no data  points  in  their
              interiors.
