[Opengrads-cooks] Point and click value return

[Colleen M. <j.c...@na...>]

Do you think a quick script that returns a value from a displayed map  
when you point and click on it would be useful for the cookbook?

This is a sample session:

ga-> d va
ga-> val_return va
Click at top of map to clear mouse clicks
Then click on map for point of interest
Click near bottom of the screen to quit
