grabbing typo fix
Add 'progress' to 'result'

I have a use case on a real live project to report both 
page progress and score for a SCORM-style course. I imagine 
this is a common use case. I'm surprised this hasn't come up 
before actually. 

I think the solution proposed is quite neat and simple. I don't
think an extension would be appropriate for something so common.
changed language of score and progress; reordered result properties

I did consider having just one score object property and changing its use based on verb, but since we have separate completion and success properties, I thought separate progress and score properties made sense too. 
full stops
Added 'units' property to 'score' object

also fixed a mis-written </tr> and inconsistent capitalisation. 
removed progress and units
Changed activity to experience. Toned down reference to extension.
