[gradsusr] write 4-d data using fwrite in grads

[Jennifer Adams]

You have to loop over T and then Z and write out one 2-D grid at a  
time. Something like this:

'set gxout fwrite'
'set fwrite -ap myfile.dat'
t=10
while (t<=200)
   'set t 't
   z=1
   while (z<=17)
     'set  z 'z
     'd var'
     z=z+1
   endwhile
   t=t+1
endwhile
'disable fwrite'
