[gradsusr] Shaded plot only for values above a minmum

[Jeff Duda]

use the ccols command to manually set the color levels.  If you have N
contour values, you need N+1 colors, the first one in the list is the color
corresponding to values below the lowest contour.  Set that to 0
(background), so that it will appear not to color values below your minimum
contour value.  See the controlling
colors<http://www.iges.org/grads/gadoc/colorcontrol.html> section
of the documentation index for more information.
