-- 059: Personal "container" course for standalone quick lessons
--
-- A teacher who just wants to author a single lesson (without manually
-- creating a whole course) gets a hidden personal container course
-- (is_personal = 1, one per teacher). Quick lessons are added there.
-- The course catalog hides personal containers from everyone except their
-- owner (see courseController.list).
