  19  // BasicLTI4Moodle is an IMS BasicLTI (Basic Learning Tools for Interoperability)
  20  // consumer for Moodle 1.9 and Moodle 2.0. BasicLTI is a IMS Standard that allows web
  21  // based learning tools to be easily integrated in LMS as native ones. The IMS BasicLTI
  22  // specification is part of the IMS standard Common Cartridge 1.1 Sakai and other main LMS
  23  // are already supporting or going to support BasicLTI. This project Implements the consumer
  24  // for Moodle. Moodle is a Free Open source Learning Management System by Martin Dougiamas.
  25  // BasicLTI4Moodle is a project iniciated and leaded by Ludo(Marc Alier) and Jordi Piguillem
  26  // at the GESSI research group at UPC.
  27  // SimpleLTI consumer for Moodle is an implementation of the early specification of LTI
