[gradsusr] using EDEF to create an ensemble in Grads

[Jennifer Adams]

Hi, Jeff --
You appear to have neglected to add 'options template' in your  
descriptor file. Also, if all your ensembles are the same length and  
have the same start time, you can simplify your edef as  'edef 7 names  
ysu myj ... boulac '
