[gradsusr] Diagnostics in Ctl File?

[Jeff Duda]

Mason,
There is a good example of how to code temperature advection in the page
for the cdiff command: http://www.iges.org/grads/gadoc/gradfunccdiff.html
The reason for all of the crazy manipulations is because the data points on
your grid are not uniformly spaced on the globe.  Thus corrections have to
be made to get the correct distance between individual grid points.
