      public class StudentOverlapConflict
      extends StudentConflict

  Student overlapping conflicts. This criterion counts student overlapping conflicts between classes. An overlapping conflict occurs when two classes that are attended by the same student (or students) are overlapping in time (i.e., `TimeLocation.hasIntersection(TimeLocation)` is true).
