The entrypoint for defining your web interface, such
as controllers, views, channels and so on.
This can be used in your application as:
use MetaWeb, :controller
use MetaWeb, :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. Instead, define any helper function in modules
and import those modules here.
