* rename to static_type and impl Deref/Mut

* Improve type substitution in codegen so that concrete types can be swapped in

* A couple of comment tweaks and no need for a macro export

* Extend type substitution logic to work recursively on destination type

* cargo fmt

* Fix a couple of comments

* update ui test outpuot

* Add docs and missing_docs lint
