What's your thoughts on adding .pynb files into the mix?

One difference between using .ipynb compared to .py files for algorithms, is the visual flexibility provided by markdown cells in .ipynb files. Here's an example of a markdown cell accompanying an algorithm.

markdown_render

Benefits of markdown cells include:

• Flexible layouting with support for headers
• The markdown cells support mathjax, so the inherent maths related to an algorithm can be written simply, and displayed nicely.

markdown_raw

There are also other benefits of .ipynb files, related to the possibility of including separate python cells:

• It's possible to have python cells that output visualisations
• It's possible to have python cells dedicated to parts of an algorithm.

I think all of these benefits contribute to educational scaffolding, which is in the spirit of this repository. I don't suggest replacing the .py files, as scripts themselves are executable and easy to use, but a section dedicated to .ipynb files is a way to provide more than just a script, in case anybody wants to learn more. It's worth pointing out that .ipynb files can include hyperlinks too which can be lead to further resources.

Just an idea, what are your thoughts on it?
