Applied the following changes to various testcase classes:
- Namespaced with component[\level2-API]
- Moved to level2-API subdirectory when required.
- Fixed incorrect use statements with leading backslash.
- Remove file phpdoc block
- Remove MOODLE_INTERNAL if not needed.
- Changed code to point to global scope when needed.
- Fix some relative paths and comments here and there.
- All them passing individually.
- Complete runs passing too.
Variants should also be treated like random questions in the sense that
a summary row
should be displayed for them as well.
This commit deals with handling variants.
Also the name of the calculated_random_question_summary class has
changed to
calculated_question_summary to be more generic as the summary row is not
specific to random questions only.
Also removed the protected function too_many_subq_and_or_variant_rows
and the const SUBQ_AND_VARIANT_ROW_LIMIT as they were not being used
anymore.
