* Reorganize the book.
This PR has one unfortunate change, which is that the README.md and
CONTRIBUTING.md files in the book are symlinks to files in the parent
directory. The motivation for this is to ensure that we don't maintain two
copies of the same data, and that the landing page of the website matches the
landing page of the Github repo, etc. However, I'm not sure whether these
symlinks will work correctly on Windows.
The alternatives are:
- Duplicate the contents of the files and expect that people will know to keep
them in sync;
- Use relative links `../../README.md` in the `SUMMARY.md`. This seemed like
it caused mdbook to dump the rendered files into the repository root rather
than keeping them in the `book` directory.
- Use a symlink (chosen option). This may not work on Windows but I think that
the worst outcome would be that the book would be unbuildable unless someone
used WSL or something. This seems like the least bad option.
* Remove symlinks in favor of #include
Turns out the symlinks aren't required!
