Help with incremental conversion to OCaml values

The Clone fix was already done in #17. What is the use case of the impl<'a, A> ToOCaml<A> for OCaml<'a, A>?

[g2p]

It's useful for converting containers while using something other than the normal ToOCaml implementation on every element; see this test: https://github.com/g2p/ocaml-interop/blob/ocamlbox/testing/rust-caller/src/lib.rs#L274

[tizoc]

@g2p oh I see. That makes total sense. Will come back to this once #17 is merged.

Can you rebase this on top of the current master? The Clone/Copy stuff is not required anymore.

Also, note that on the new ocaml-interop OCamlAllocResult doesn't exist anymore, OCaml<T> values are now returned directly.

I'll drop this one (it didn't work well with the new lifetimes on ToOCaml, as I recall);
there's a commit in #24 that exposes cons and makes this unnecessary in the list case.
