* Exercise submission

* This script allows to run an exercise. According to the exercise type, questions
|
|
* can be on an unique page, or one per page with a Next button.
|
|
*
|
|
* One exercise may contain different types of answers (unique or multiple selection,
|
|
* matching, fill in blanks, free answer, hot-spot).
|
|
*
|
|
* Questions are selected randomly or not.
|
|
*
|
|
* When the user has answered all questions and clicks on the button "Ok",
|
|
* it goes to exercise_result.php
|
