Notice: Undefined variable: format in _taxonomy_csv_vocabulary_import_process() (line 421 of /var/www/dev/fgao/cstc/sites/all/modules/taxonomy_csv/import/taxonomy_csv.import.api.inc).

Hi
I find a obviously bug in this module.
In line 421 of "taxonomy_csv.import.api.inc" file, it check $format but did not define this variable anywhere. I think there should be $options
Attachement is my patch.
Thanks
