[gradsusr] monthly to yearly script

Sat Nov 7 15:13:36 EST 2015

the 'close' command does not operate as it does in Matplotlib or MATLAB in
closing figures. In Grads, 'close' closes the data file. Since your open
statement is outside the loop, that probably explains why you are only
getting one map. The output from the script should be cluing you into that
fact by saying something like "CAN'T DISPLAY - NO FILES OPEN"
