== Mark Deduction For Late Evaluation Submission ==
Refer to ticket #364

== Requirements ==
An admin/instructor:
* Should be able to set mark penalty scale for late evaluation submissions.
The students:
* Should be notified about the mark penalties for late evaluation submissions.
== DB Changes ==
* Two new tables have been added : Penalty, and User_grade_penalty.
* Run the attached SQL queries to update your current database.
{{{
#!sql
CREATE TABLE `penalties` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `event_id` int(11) DEFAULT NULL,
  `days_late` int(11) NOT NULL,
  `percent_penalty` int(11) NOT NULL,
  PRIMARY KEY (`id`),
  KEY `fk_events` (`event_id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1;

ALTER TABLE `penalties`
  ADD CONSTRAINT `fk_events` FOREIGN KEY (`event_id`) REFERENCES `events` (`id`) ON DELETE CASCADE;
}}}
== 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.
