A module that keeps using definitions for controllers,
views and so on.

use Pleroma.Web, :controller
use Pleroma.Web, :view
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
below.
