[gradsusr] Area average only for California

[rjmera]

Hi, all. I've looked at some of the previous posts on this subject but I 
wasn't sure if it covered what I wanted to do. What I'm trying to do is 
to get area average for an irregular polygon. To be specific, the state 
of California, for example. This would exclude other states in the 
vicinity and the ocean. How should I proceed?
