Tracking in the Framework xAPI and SCORM and others

We need to start using xAPI for tracking our learning in Adapt (because it's the future!).

Some work has been done already (see ABU-1116)

Discussion Topics

• review current progress and plan of attack
• Maintain existing spoor plugin for backwards compatibility?
• Port event capture code from spoor to core framework?
• Review events fired by components/extensions/framework -
  • Are we triggering what we need to?
  • Are events consistent?
• xAPI extension? (new Scorm one too?)
• Additional tracking types - in addition to SCORM/xAPI?

Tentative Actions/Conclusions:

• Serialization should stay within the protocol (SCORM, xAPI, etc.)
• Stateful session will move to adapt core
• Possibility of implementing one tracking query that each protocol can query to determine the tracking status (rather than a lot of individual tracking calls to core)
