- Ensure that only a course import is saved to the draft branch and then
published. A content library has only a single 'library' branch.
- Add a fields parameter to the create_library call so the call has the
correct number of parameters.
- Add tests which import content libraries using different test methods
and with different branch settings.
- Add test which imports a content library and then exports it.
- Use XBlock module version that supports XML-serialized String of None.
- Add re-import of content library and equality comparison to test.
- Allow get_items to be called on LibraryLocators.
