Yes, I think this is going in the right direction. However, I'd hold off on doing "instant" events at the moment and only use events with a distinct beginning and end. That is, basically, add a label to GenericActivityStart and GenericActivityEnd and remove GenericEvent.

Let me do another pass over the existing TimeLine events and mark them as either "remove" or "start-end"...
