/**
 * The purpose of this feature is to quickly remove all user related data from a course
 * in order to make it available for a new semester.  This feature can handle the removal
 * of general course data like students, teachers, logs, events and groups as well as module
 * specific data.  Each module must be modified to take advantage of this new feature.
 * The feature will also reset the start date of the course if necessary.
