/**
 * @package chamilo.survey
 *
 * @author unknown, the initial survey that did not make it in 1.8 because of bad code
 * @author Patrick Cool <[email protected]>, Ghent University: cleanup,
 * refactoring and rewriting large parts of the code
 * @author Julio Montoya <[email protected]>, Chamilo: Personality Test
 * modification and rewriting large parts of the code as well
 *
 * @todo check if the user already filled the survey and if this
 * is the case then the answers have to be updated and not stored again.
 * @todo performance could be improved if not the survey_id was
 * stored with the invitation but the survey_code
