008 * Reservation override. A special instance of the {@link IndividualReservation}
009 * for a particular student (or students) that allows for defining whether
010 * it must be used, whether time conflicts are allowed, and whether it
011 * is allowed to assign the student over the limit. This class is intended to be used
012 * to model student overrides.
