defmodule Default.Behaviour do
  @moduledoc """
  Creates a behaviour that carries its own default implementation.

  When used into a behaviour module, when that module in turn is used, all functions
  defined on it are given to the using module.
  
  This allows you to have concrete implementations of the behaviour's default functionality
  for testing, unlike cramming them all into a __using__ macro.
