Notes

Checklist

• PR has an informative and human-readable title (this will be pulled into the release notes)
• Changes are limited to a single goal (no scope creep)
• Code passed the pre-commit check & code is left cleaner/nicer than when first encountered.
• Any change in functionality is tested
• New functions are documented (with a description, list of inputs, and expected output)
• Dataflow documentation has been updated if adding/changing functionality.

I've also been adding an example of how to execute things...

[zilto]

perhaps we could automate that by capturing what's under if __name__ == "__main__":

[skrawcz]

Agreed. Let's ship this first, and then modify the code generation script to pull that?

[skrawcz]

add doc strings.

Also add limitations, and how to modify/extend?

[skrawcz]

just need to add image, and then merge away!
