== Implementation ==
* An instructor or admin can choose to apply ONE late penalty scale to an event.
* For now, the late penalty applies to all of the groups that are assigned to an evaluation event.
* By default, the penalty scale will have increments of one day.
* The penalty scale can still be modified after the initial setting.
