Better documentation for rust-python interop

[spease]

Hey, this is great. It's exactly what I need for a project I'm working on. Is there any documentation or examples on how to use it in a project using Rust code with tokio that calls python with asyncjo/aiohttp? Thanks much.

why do you need aiohttp, why can't you use hyper on rust side?

Porting an existing codebase that's doing http calls itself with aiohttp client

ok.
there is no example, but here how you can do this

1. import aiohttp (example https://github.com/PyO3/tokio/blob/master/src/utils.rs#L53)
2. call aiohttp (example how to call https://github.com/PyO3/tokio/blob/master/src/utils.rs#L193)
3. downcast result into PyFuture. PyFuture implements Future trait and you can wait for result in rust
   this future resolves into PyObject, it is ClientResponse object.

it is not very pleasant experience :)
