Reloading from Jupyter Notebooks is not supported

[nathanielobrown]

Seeing as this is a super early stage project, I assume you just haven't got to this yet and this exception will demonstrate the issue. I was trying to use reloadr on a class I defined in a JupyterNotebook.

Hello,

I did not design this tool with Notebooks in mind — I usually re-run the cell in notebooks to reload their code — but it should be possible to add support for notebooks as well. I'll have a look at it.

Great, thanks!
