Hi folks

I have completed the updates to both the web site description and the RFC:



The RFC references the prototype code. There is still a bug or two in the PMIx_Group_invite implementation, and so I haven’t formally submitted the PR yet.

Please take a look and let me know what you think. I’ll be out on vacation for a few days, but will pick up the implementation again when I return.
