Research and more information

Hi Folks
I had an action item to think about how to keep sources for each pattern.

I made a suggested draft at :
 The COGA Design Guided -  Research and more information
https://docs.google.com/
<https://docs.google.com/document/d/1U3gdQesJHTmLZ2H62_23olZD3jZ-5SEMBZxhb-RsQsY/edit#heading=h.mxwk9an68v1m>

we can also port it back to the wiki once the collaboration is done.

All the best
Lisa
