> CsvStringify crashes in case of tuple in tuple, t.e. ("a", True, (1,5))
> Looks like, mistyping in CsvStringify._map()
> {code}
> def _map(self, value):
> if isinstance(value, (tuple, list)):
> return "(" + b", ".join([self.map(x) for x in value]) + ")"
> else:
> return str(value)
> {code}
> self._map() should be called
> But this will affect write_csv() and read_csv().
> write_csv() will work automatically
> and read_csv() should be implemented to be able to read Tuple type.
