Just upgraded a [collection of notebooks](https://github.com/ctkelley/NotebookSIAMFANL) from PyPlot to PythonPlot. This stopped chronic kernel deaths and eliminated the need (I think) for running single threaded.

There were very few things I had to change and the only downside is the nagging from CondaPkg and the occasional
