def gen_rows0(self):
return self.gen_rows(*(self._get_csv_reader_generators()))<EOL>
Iterate through all rows in all files file.

        The file is specified by the class - there is one class per
        table.  This opens the file, does basic sanitaition, and
        iterates over all rows as dictionaries, converted by
        csv.DictReader.  This function opens files from both .zip and
        raw directories.  The actual logic of converting all data to
        Python is done in the .gen_rows() method which must be
        defined in each subclass.
