Rename `pos_label_str` to `pos_label` everywhere. by desilinguist · Pull Request #706 · EducationalTestingService/skll

I checked out the branch and grepped all the _label_str and found the following occurrences of other_label_str. Rest looks good to me.

./tests/test_classification.py:252:        pos_label, other_label_str = 'B', 'C'
./tests/test_classification.py:254:        pos_label, other_label_str = 2, 1
./tests/test_classification.py:256:        pos_label, other_label_str = 'FRAG', 'NONE'
./tests/test_classification.py:263:        index_label_dict = {0: other_label_str, 1: pos_label}
./tests/test_classification.py:265:        sorted_label_list = sorted([pos_label, other_label_str])
