docs: Return the :class:`DvClass` with the given name
  
          The name is partially matched against the known class names and the first result is returned.
          For example, the input `foobar` will match on Lfoobar/bla/foo;
  
          :param str class_name:
          :return: the class matching on the name
          :rtype: DvClass
