Samuel's notebook rewrite?

[Robert Jacobson]

Where is the latest code for Samuel's interface rewrite? His github repo hasn't been updated in a few months, and so I'm wondering if active development is happening elsewhere. Has it been pulled into the official sagemath/sagenb repo? If so, how do I enable it? 

If I can get up to speed on the development process and the codebase, then there is the potential that I can contribute.

The pull request is this: https://github.com/sagemath/sagenb/pull/93 and
as far as I know there are no other (up to date) forks of this. It
requires a rebase since it won't apply to current master.

On this topic - should we import all of Samuel's work as a new branch
called "new-ui" on sagemath/sagenb? Then anyone can send pull requests
to that branch with bug fixes and enhancements.
