Proposal to close open issues with quad tree serialization format

["=Drummond Reed" <drummond.reed@xdi.org>]

In preparation for tomorrow's call, I finished writing up a proposal to settle the final issues with the JSON quad tree format—namely the treatment of what we have been calling "empty context nodes", but which I realized in preparing the formal proposal needed more precise names (because there are two cases):

1. Solitary context nodes.
2. Object-only context nodes.

Explanations of these terms and the proposed rules are in bold in this section of the wiki page.

The special examples I created to illustrate these rules are at the bottom of the page.

Talk to you on the call at 9AM PT tomorrow.
