[gradsusr] extract values from function

[Jeff Duda]

When you say "trend", do you mean time derivative?  Over what domain do you
want to find the max and min?  If it's a spatial domain, there is a well
known set of script command lines that can find an areal max for you.  It's
not one of the built-in functions of Grads, though.
