Powershell script for building documenation

Currently there are three ways to build docuemnation locally...

1. using the make scripts
2. using tox
3. typing out the raw commands python -m sphinx ...

tox is great for CI but annoying to local builds because it builds a python virtual environment. make is great for Linux and MacOS systems, but does not work well with Windows' command prompt and Powershell terminals. You can use the make command in the WSL terminal, but the building process is slow because the build files exist on the Windows file system and not the virtual Linux file system. One can run the basic build commands in Powershell, but it's a bit annoying trying to remember what the correct command is. I'm proposing to look into making a Powershell script that is analogous to the make script for Windows users.

Inspect the existing make scripts and tox configuration, then compare them with the documented python -m sphinx ... commands. Add a Windows PowerShell equivalent that builds the documentation locally; done means the documented build succeeds without relying on WSL or a newly created tox environment.
