+  The entrypoint for defining your web interface, such
+  as controllers, views, channels and so on.
+
+  This can be used in your application as:
+
+      use NolaWeb, :controller
+      use NolaWeb, :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.
