[gradsusr] dset and option template

[Jennifer M Adams]

Hi, Ivana — 
You can specify the initial time of a forecast by inserting an “i” into the temple substitution strings, e.g.
     DSET /mnt/data/hindcast/%iy2%im2%id200/data_%f3 
This is mention in the documentation on templating: http://cola.gmu.edu/grads/gadoc/templates.html
