API Docs for end-users

[oxinabox]

We don't seem to have API docs?

[gdalle]

There's the README, but do you mean an actual documentation website à la Documenter.jl?

[oxinabox]

Yes

Right now nothing explains what eg gradient or hessian is. What it's return types are etc

[oxinabox]

those are related.
But in particular I want API docs for gradient, hessian, jacobian etc etc.

This is solved in the main branch and corresponding dev docs
