[gradsusr] Creating a grads file from station data

[Jennifer Adams]

GrADS requires a special format for a binary file containing station data. You cannot just use a DSET entry in a descriptor file to point to you your ascii data file. Converting your ascii file to this special binary format requires some customized programming. The documentation page at http://iges.org/grads/gadoc/aboutstationdata.html has some code samples to help you get started.
