[gradsusr] Help Displaying NetCDF File

[L.B.]

Thanks, Jennifer, that did the trick! I also did need to add the
yrev options as well to flip the grid. As to the levs entry under the vars
section Jeff, it seemed to work either way with 1 or 0. I left it at 0 like
you mentioned since technically it doesn't have a vertical dimension.
