[gradsusr] Help scripts for WRF output in grads

[Jeff Duda]

The ARWpost software also includes utilities (look in the util
subdirectory) that can make a .ctl file from your WRF history dump file so
you can view the raw output in Grads without first post-processing it.  It
would probably take you less time if you go this route, but you will have
to manually compute relative humidity in Grads then.  It isn't required of
you to compile or run ARWpost to use these utilities.
