Add explanatory inline comments to Python example programs [DOCS]

**What section of the docs could be improved? **
The entire collection of the Nillion Python Starter programs.

What part(s) of the docs would you like to see updated?
Comments which explain which parts of the outputs and bits of information are available to which parties based on the definitions.
