        Run a minimal twisted.web server on the specified C{port}, bound to the
        interface specified by C{host} and logging to C{logFile}.

        This function will run the default reactor for your platform and so
        will block the main thread of your application.  It should be the last
        thing your klein application does.

        @param host: The hostname or IP address to bind the listening socket
            to.  "0.0.0.0" will allow you to listen on all interfaces, and
            "127.0.0.1" will allow you to listen on just the loopback interface.
        @type host: str

        @param port: The TCP port to accept HTTP requests on.
        @type port: int

        @param logFile: The file object to log to, by default C{sys.stdout}
        @type logFile: file object

        @param endpoint_description: specification of endpoint. Must contain
            protocol, port and interface. May contain other optional arguments,
             e.g. to use SSL: "ssl:443:privateKey=key.pem:certKey=crt.pem"
