Add examples that don't rely on notebooks

[ivyleavedtoadflax]

The current examples are in a notebook, which:

• Don't render in github (for some reason)
• Require additional dependencies such as jupyter

Let's create some example scritps which can be more easily read and executed.

@ivyleavedtoadflax the notebooks seem to render, but do you need any help creating some scripts?
