[gradsusr] Lats4d multiple functions

[Mike Fiorino - NOAA Federal]

hi Brian,

do lats4d -h to get a list of options...  see -func command line option

you can do multiple functions in an expression, e.g., 
ta=ave(sum(precip,lon=0,lon=360),time=0z1sep2013,time=0z2sep2013)

the simplest approach would to do multiple calls of lats4d for each expression to separate 
.nc...
