  The entrypoint for defining the web interface, such

  This can be used in the application as:

      use DemoLT.AdminWeb, :controller

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

  Do NOT define functions inside the quoted expressions
