******************************************************************************
* Max Half-Days Constraint
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* The MaxHalfDays constraint limits the number of half-days of week during which
* the given set of classes are taught.
* It has one parameter: a maximal number of week half-days during which the given
* set of classes can be placed.
* A day is split by noon (which can be changed using General.HalfDaySlot parameter).
* A class starting before noon is considered a morning class (despite of its end),
* a class starting at noon or later is considered an afternoon class
* For instance, a reference MaxHalfDays:4 translates to a maximum number of 4 half-days
* a week.
