[gradsusr] Help with fwrite

[Mike Fiorino - NOAA Federal]

hi Nick,

the xdef/ydef in seac4rs_all.ctl defines the grid the pdef grid is interpolated *to* in 
grads...  take out the pdef in the ustorm.ctl and it should work...also check the size of 
the .bin file it should be ni*nj + 0 bytes (if you use the -sq option in set fwrite the 
output is f77 sequential)
