* 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
*
* Notice : This script is also used to show a question before modifying it by
* the administrator
*
* @author Olivier Brouckaert
* @author Julio Montoya <gugli100@gmail.com>
* Fill in blank option added (2008)
* Cleaning exercises (2010),
* Adding hotspot delineation support (2011)
* Adding reminder + ajax support (2011)
* Modified by hubert.borderiou (2011-10-21 question category)
