The Analemma Package - Sundials in Python

[russellgoyder]

I have used GAlgebra in a Python package called Analemma, which is the term for the path traced by the sun (or its shadow on a sundial) at the same time each day throughout the year.

It includes both a numerical and symbolic implementation of sundial math, the latter using GAlgebra, so I thought it may be of interest here as an example of what you can do with GAlegbra, and potentially as a source of tests for the package.

I would like to express my sincere thanks to all the contributors for creating GAlgebra. Many years ago I used Maple for the original implementation, and it feels great to be able to share a version of it using tools available to everyone.
