+Builds a PSGI application coderef for the catalyst application C<$c> using
+L</"$c->setup_psgi_app">, stores it internally, and returns it. On the next call
+to this method, C<setup_psgi_app> won't be invoked again, but its persisted
+return value of it will be returned.
+
+This is the top-level entrypoint for things that need a full blown Catalyst PSGI
+app. If you only need the raw PSGI application, without any middlewares, use
+L</"$c->raw_psgi_app"> instead.
