[Isod-rg] OGF ISOD-RG use case document

[Chin Guok]

Hi all,

I apologize for starting this late.  I've out together a quick skeleton 
of the document for folks to throw fruit at.

The document can be found at 
https://docs.google.com/a/lbl.gov/document/d/1UfI1kY9ZU4I9SUjlNg4QpbJF9B9LF-vpx6Pb11OqLjM/edit?hl=en_US

It's very basic, and needs quite a bit of work, but I wanted to get a 
sense from people if something like this is useful, or if they would 
rather take a completely different approach.

I'm open to suggestions and very much welcome anyone who wants to 
contribute to the document.

Please feel free to make changes and comments to the document.

Thanks!

- Chin
