       Tatsuhiko Miyagawa

       Plack::App::Cascade is a Plack middleware component that compounds several apps and tries them to return
       the first response that is not 404.

       new
             $app = Plack::App::Cascade->new(apps => [ $app1, $app2 ]);

           Creates a new Cascade application.

       add
             $app->add($app1);
             $app->add($app2, $app3);

           Appends a new application to the list of apps to try. You can pass the multiple apps to the one "add"
           call.

       catch
             $app->catch([ 403, 404 ]);

           Sets which error codes to catch and process onwards. Defaults to 404.
