[Xerte] passing scores through to the scorm api

[Hamish Dewe]

Thanks for the pointer Julian.

I've found a method that works for me, so I'll post it here just on the 
off chance that it's useful for others.

Moodle (1.93) only partially supports SCORM 2004, so I went with their 
implementation of the api for 1.2.
Dealing with setting, extracting and processing cmi.suspend_data looked 
to be too convoluted.
My answer was to use cmi.objectives.n.score.[min/max/raw] (n is an 
integer, starting from 0,My proof of concept SCO sends these to the LMS 
using setValue() on submission of each exercise, keeps a running tally 
and sends cmi.core.score.[min/max/raw] to the LMS on exit. Moodle keeps 
these records in table 'mdl_scorm_scoes_track' where 'mdl_' is the 
default table prefix. For students resuming the piece, these values can 
be returned via the api in the usual way (getValue()).

If anyone's looking at what Moodle currently supports, check the 
individual data models in ../moodle/mod/scorm/datamodels/scorm_[12/13]js.php
