defmodule ProperCase.Plug.SnakeCaseParams do
  @moduledoc """
   A helpful plug that converts your incoming parameters to
   Elixir's `snake_case`

   Plug it into your `router.ex` connection pipeline like so:

    pipeline :api do
      plug :accepts, ["json"]
      plug ProperCase.Plug.SnakeCaseParams
    end

  Enjoy :)
