  A module that keeps using definitions for controllers,

  This can be used in your application as:

      use SignDictWeb, :controller

  The definitions below will be executed for every view,
  controller, etc, so keep them short and clean, focused
  on imports, uses and aliases.

  Do NOT define functions inside the quoted expressions
