Add Documentation

[EthanC]

CallofDuty.py documentation will be automatically generated using Portray once support for NumPy docstrings has been added.

This will produce a beautiful, static documentation site based on MkDocs which will then be hosted on GitHub Pages.

Portray seems to work on the codebase. I only had to change the following line in pyproject.toml

name = "callofduty"

Then I was able to run portray server --host 0.0.0.0 and it seemed to work just fine.

Is this ever happening?
