MWW 2024-11-13 task notes

DONE 2024-11-17: Create an index file: if there's no README.md or Index.md, create one, with content like "This is the home page of this website".
Something like the following. If the user enters a title, use that instead of "Home Page".

# Home Page

This the home page of this website.

2024-11-17: implementation notes:
- NXC requires a README.md at the root; this get copied to index.md during build
- DONE: if there is an existing index.html at the root, rename it to guard against overwriting what gets built
- pypi version bumped to 0.3.0
