Allow a show/hide date range for the "Let Students See Their Quiz Responses (Incorrect Questions Will Be Marked in Student Feedback)" quiz setting.

In order to maintain test security, instructors often want to limit students from viewing their quiz results until after the due date for the quiz has passed.  Currently, the correct answers can be set to be shown and hidden on given dates, but students will still be able to see the questions, their responses, incorrect answers, and feedback prior to this date, and if an instructor wants students only to be able to see their results but not correct answers, the only way to do this is to uncheck the "Let Students See Their Quiz Responses" option then manually go back and enable it once the due date (or other chosen date) has passed.

Please add a date range selector like the one that is there for Let Students See the Correct Answers:
