* Display the grouping a course module belongs to on the course page - for course managers only.
* When adding users to groups, display the groups a user already belongs to.
* Added an overview report that shows groupings, groups and members for a course.
* Added a dialogue to automatically create groups and assign members based on either the number of desired groups or the number of desired users per group.
