Notebook cell vim bindings

Special Thanks

I want to acknowledge Alisue and his excellent work creating vim bindings for Jupyter notebooks. I hope this extension can meet the high bar his work set.

Modes

This extension splits Jupyter edit mode into two modes: Vim command mode and Vim insert mode. Three editing modes now exist: Jupyter command, Vim command, and Vim insert.
