Investigate MYMC++ publish/build strategy

We will need to build MYMC++ to a single file that people can easily download and run.
A tool called `pyinstaller` seems to be the go to recommendation.
Need the resulting application to be able to be:
- Run as an "app", e.g. clicked in Windows explorer and opens a gui.
- Run as a CLI tool, e.g. ran from the command line and able to get input/print output and take different arguments.
