Passed a list of applications, ``Cascade`` will try each of them
in turn. If one returns a status code listed in ``catch`` (by
default just ``404 Not Found``) then the next application is
tried.
If all applications fail, then the last application's failure
response is used.
Instances of this class are WSGI applications.
