 * iAssign allow insertion of new "interactive Learning Modules" (iLM),
 * at any times, by the Moodle administrator.
 * It cames with some iLM from Laboratory of Informatics in Education (LInE),
 * like iVProg (www.matematica.br/ivprog) and iFractions (www.matematica.br/ifractions).
 * The purpose of this scritp is to insert theses initial iLM in your iAssign module.
 * 
 * - v 1.5.5 2023/05/04
 *     + Added new version of iVProg 2023_05_04 with Portugol/English direct encoding
 * - v 1.5.4 2021/12/23
 *     + Added new version of iVProg 2021_11_30_22_06

 *     + Removed all commands associated to 'upgrade'
 * - v 1.5.2 2020/08/03

 *     + New version of iHanoi 1.0.20200803
 * - v 1.5.1 2020/05/28-30
 *     + Avoid to update one iLM causing colision with other instance of the same iLM
 * - v 1.4 2013/09/19
 *     + Insert general fields for iassign statement (grade, timeavaliable, timedue, preventlate, test, max_experiment).
 *     + Change index field 'name' in 'iassign_ilm' table to index field 'name,version'.
 * - v 1.2 2013/08/30
