Quickly turn your math mode expression into cropped png, svg, or pdf.
Then you can drag and drop it into slack or illustrator or whatever.
This is basically just a wrapper around the standalone document class.

Pass your math expression (in quotes) on the command line. It will be
typeset in the align* environment by default, unless you pass --nomath,
in which case you can put the environment in the expression too.

"""noint: Shield a code block or function from SIGINT.

Based on: http://stackoverflow.com/a/21919644/487556.

Useful for running training loops in Jupyter: if your learning
step is inside a `with noint:`, when you want to interrupt your
training routine, you can do that without getting halfway through
some set of operations and leaving the model state inconsistent,
which would make it impossible to rerun the cell without
restarting the whole training loop.
