Add documents for MkDocs website integration

[ningerson2002]

This pull request provides the documents needed to deploy a documentation website. We hope to implement automated API documentation in the future and are looking for further insight into how we may do this.

Inside of this PR you are trying to push multiple .DS_Store files. Please delete these, they should never be pushed to the main branch. Once those two files are removed we can look more in depth at the content of this PR. Thanks!

Thanks for reviewing this PR @burgess01. In addition to removing these files, I will add that we should try to avoid committing the files generated by MKdocs and instead include steps in GitHub actions to do that automatically after changes are pushed to main branch
