[gradsusr] Standard Deviation

[Muhammad Yunus Ahmad Mazuki]

By using the standard deviation formula (minus the average part), constant
the longitude and level for example
set t 1 48
set lon 180
set lev 200
set lat -40 40

ave1=ave(sstk,t=1,t=48)
stdev2=sqrt(pow(ave1-sstk,2))
This however is not seasonal standard deviation.
