-- later refactor learning in multimarker itself

-# TODO 
-- cleanup code in the screenAsPortal examples
-  - then make that the example for multi marker with a simpler 3d
-- put learner in the same .html to avoid reload
-- maybe do a threex-armultimarkersimple.js which regroup the usual usage of multi marker
-  - thus the boilerplate isnt too big when it is repeated all the time
-- clean up learner
-  - remove arToolkitContext
-  - have caller listen to the event and call areaLearning.onSourceProcessed()
-- we learn while we play ? thus the result are getting better and better
-- able to play when all marker are markers as learned
-- do nice visual on each marker - phase 'scan all the markers'
-- once all markers are learned we can start playing
