Integrate or communicate CI with Moodle

[eluser]cahva[/eluser]
Because CI session defaults using from COOKIE(bad) or database if set. If you need moodle's session information, using native session is the way to go. Benefit of using this native session lib for CI is that you can access those session variables set by moodle the same way you normally use sessions in CI eg. $this->session->userdata('some_session_var_set_from_moodle')
