      Equivalent to functools.partial performance, base_args are preprended to the
      positional arguments given during object initialization and base_kwargs are
      updated with the kwargs given later.
  
      Args:
        cls: The base class.
        *base_args: Positional arguments to be applied to the subclass.
        **base_kwargs: Keyword arguments to be applied to the subclass.
  
      Returns:
        A subclass of the input class.
