It'd be nice to integrate this with nilla (especially so as not to have
to maintain double the lockfiles/etc.) but for now I guess this is OK...

We've chosen to go with leptos as our server as, since as we're writing
in rust, it'll allow us to write the backend/frontend in the same
language and nicely call between them.

This is their example project, modified to use a later edition of rust
and to remove the license (their sample is Unlicense) since as I plan to
AGPL this.

If you're interested in creating something like this yourself, please
look here:
