"""
Using generator functions to represent simulations
==================================================

A quick example of how to model a long/complex calculation using a generator function (a function containing
'yield') in Python.  In the example below, we set-up a calculation; get intermediate results from it; send
new data to it, and - using a new feature in Python 3.13 - get a finished result at the end.

Ultimately, do what's clearest, and easiest to understand and maintain.
