[svn r21162] Not enabled improvement to SCORM. Doesn't work properly in all circumstances, so better disabling it, but the code is almost correct.

* This script contains the server part of the xajax interaction process. The |
||||||
|
* client part is located in lp_api.php or other api's. |
||||||
|
* This script exists exclusively to comply with the SCORM 1.2 rules notes that |
||||||
|
* say that if the SCO doesn't give a status throughout its execution, then the |
||||||
|
* status should be automatically set to 'completed', then the score should be |
||||||
|
* evaluated against mastery_score and, if a raw score and mastery_score value |
||||||
|
* are set, assign the final status based on that. |
||||||
|
* As such, this script will: |
||||||
|
* 1 - check the current status for the given element is still 'not attempted' |
||||||
|
* 2 - check if there is a mastery score |
||||||
|
* 3 - check if there is a raw score |
||||||
|
* 4 - if 2 or 3 are false, change the status to 'completed', else compare |
||||||
|
* whether the raw score is higher than the mastery score. If not, the status |
||||||
|
* will be set to 'failed', if yes, the status will be set to 'passed' |
||||||
|
* 5 - update the status in the table of contents |
