Merge branch 'release/0.12.0' into develop
Remove some unnecessary parentheses.
Add additional unit test for kappa to detect future issues with missing ratings.
Automatically remove the extra config files that are created
as part of ablation.
Fix issue #56. Make model_type a requirement argument. PEP8 cleanup.
Add a couple lines to skip IDs that are in feature files, but not in cv_folds file. Prints a warning instead of crashing like it does now.
Better strategy: create named temporary files and then delete
each one as done inside _run_configuration_without_feature()
Fix crash in test_skll.py because model_type is no longer a keyword argument.
Make IDs get skipped if they're not in cv_folds file when doing grid search as well.
Merge pull request #55 from EducationalTestingService/feature/remove_ablation_cfgs
