A guard implementation which supports HTTP header-based authentication
schemes.

If no I{Authorization} header is supplied, an anonymous login will be
attempted by using a L{Anonymous} credentials object.  If such a header is
supplied and does not contain allowed credentials, or if anonymous login is
denied, a 401 will be sent in the response along with I{WWW-Authenticate}
headers for each of the allowed authentication schemes.

        avatars.

        providers.

        Get the L{IResource} which the given request is authorized to receive.
        If the proper authorization headers are present, the resource will be
        requested from the portal.  If not, an anonymous login attempt will be
        made.

        Inspect the Authorization HTTP header, and return a deferred which,
        when fired after successful authentication, will return an authorized
        C{Avatar}. On authentication failure, an C{UnauthorizedResource} will
        be returned, essentially halting further dispatch on the wrapped
        resource and all children

        Handle login success by wrapping the resulting L{IResource} avatar
        so that the C{logout} callback will be invoked when rendering is

            Wrap an L{IResource} so that whenever it or a child of it
            completes rendering, the cred logout hook will be invoked.

            An assumption is made here that exactly one L{IResource} from
            among C{avatar} and all of its children will be rendered.  If
            more than one is rendered, C{logout} will be invoked multiple
            times and probably earlier than desired.

                Pass through the lookup to the wrapped resource, wrapping
                the result in L{ResourceWrapper} to ensure C{logout} is
                called when rendering of the child is complete.
