This is pretty much a WIP. Do you find it useful or want to contribute?

This seems useful. It seems like a simpler way of laying out a project than what the Sea ORM guides (and sea-orm-cli) do. I'll likely use it if I stick to Rust for the new component I'm writing, but I'm also debating using Ruby on Rails for it instead.
