WIP: Implemented a notion of a Maximum Score (and updated the Overview screen to show this)
Problems can now have a maximum score:
- This maximum score can be given when creating the problem widgets on the exam paper.
- If no maximum is given, the old default is used (the maximum value of the feedback items).
- The back-end enforces that no score larger than the maximum can be given.
- If the grader tries to exceed the maximum (either by enabling positive or disabling negative rubric items) an error is shown.
- The maximum score is shown in the question selector as well as in the feedbackpanel.
The overview page has also been updated:
- It shows the maximum score per question.
- As requested in #249 (closed) the average score (as well as std dev and median) are now shown on the overview page. More statistics should be added before the issue can be closed, but this might be a good start.
Curious to hear what you think! :)
