Panels CM

I am creating this sandox as a code exploration of Web Components as defined here: http://dvcs.w3.org/hg/webcomponents/raw-file/tip/explainer/index.html

Upon first reading about this idea the first implementation I wanted to try was to build the UI of Panels-in-page editing upon these concepts. There's only one problem, I don't know a lot about Panels' code.

Also, I will explore if using this technique would reduce code weight: http://hacks.mozilla.org/2011/11/html5-context-menus-in-firefox-screenca...
