Integrate the Mochi kernel (Jupyter/IPython) into the Mochi code base

[pya]

The kernel is still a separate project (https://github.com/Carreau/mochi-kernel). We have the permission from the author to incorporate into Mochi.

If it's easier, I can even transfer the repo to you, just ask. This was mostly an afternoon hack, but happy to see it used.

[pya]

Yes. Please transfer the repo. I might keep it as an extra repo. At least for a while. Maybe it is no ideal to make IPython a hard dependency. There might be user who do not want to use IPython because they don’t know what it is. What do you think?

[Carreau]

Tho whom should I transfer @pya or @i2y ? (or do you want to make an org)

As for IPython, that's one of the reason we renamed to jupyter, to remove ambiguity. The relevant jupyter_* libs can be smaller deps if necessary. As it's pip-installable, you can pull the deps automatically, you can always make them optional I suppose, you wouldn't be the first kernel to do so.
