This plug will take `body_params` from Plug.Conn structure
and re-render it with appropriate structure to `resp_body`.
What is appropriate structure? Take look at [Nebo #15 API Manifest](http://docs.apimanifest.apiary.io/#).
# Example:
Add to your `endpoint.ex` before Plug.Parsers plug:
plug EView
plug EView.Plugs.Idempotency
