Used to define intervals of dates, times, quantities (whose units match) and so on. The type parameter, `T`, must be a descendant of the type `DV_ORDERED`, which is necessary (but not sufficient) for instances to be compared (`_strictly_comparable_` is also needed). \n\nWithout the `DV_INTERVAL` class, quite a few more `DV_` classes would be needed to express logical intervals, namely interval versions of all the date/time classes, and of quantity classes. Further, it allows the semantics of intervals to be stated in one place unequivocally, including the conditions for strict comparison. \n\nThe basic semantics are derived from the class `Interval<T>`, described in the support RM.
