Scrubbing IPython Notebook outputs
As a git pre-commit hook.
The goal is to avoid committing outputs to your git repo, if that kind of thing is annoying to you.
pre-commit from this repo as
.git/hooks/pre-commit in your repo,
and any time you commit a notebook, all outputs will be scrubbed prior to the commit
(behaves the same as the "clear all output" button in the notebook UI).
