   Note you can also test your custom module via `Dict`'s doctests:

defmodule Dict.Behaviour do
  @moduledoc """
  This module makes it easier to create your own `Dict` compliant
  module, by providing default implementations for some required functions.


        # override default implementations if needed
      end

  The client module must contain the following functions:

  * `delete/2`
  * `fetch/2`
  * `put/3`
  * `reduce/3`
  * `size/1`
  * `update/4`

  All of which are part of the `Dict` behaviour, so no extra functions are
  actually required.

  Based on these functions, `Dict.Behaviour` generates default implementations
