Added protection of private members in CCHandler.

        self._server = server

    def __getitem__(self, name):

        logging.debug('Called method %s.%s' % (self.__class__.__name__, name))

        if name.startswith('_'):

            # Filter the private members access:

            raise KeyError('Remote name %s is private.' % repr(name))

        else:

            logging.debug('Called %s.%s' % (self.__class__.__name__, name))

            return super(CCHandler, self).__getitem__(name)
