******************************************************************************
* MaxHoles distribution constraint
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* The MaxHoles constraint limits the number of free time (holes) for an instructor
* on a day (between the first and the last class on a day).
* It has one parameter: a maximal amount of free time that an instructor can have
* on a day in minutes.
* For example, reference _MaxHoles:120_ translates to a maximum number of two hours
* of total free time between the first and the last class on a day.
* If required, having more free time is prohibited.
* If preferred or strongly preferred, the excessive free time is penalized
