[gradsusr] delete coincident isolines

[Jeff Duda]

I'm not sure of the best way to remedy a situation involving contour lines.
Another user suggested making your field periodic (if you are plotting
something like wind direction in degrees, you may be in luck) so that you
don't have to skip so many contours over such a short distance.
