The comment for OnEventProcessingStarted() already mentions this. You can remove
the comment from here.

Done. 

I realize it's duplicated documentation, but the reason I added it (and would
like to add more) was because EventProcessor::OnEventFromSource() is the most
central and important method in the whole event processing system. I assume the
frequency of other developers referencing this method during related debugging
would be high, so leaving it as a wall of code feels like a bit of a disservice.

   OnEventProcessingStarted(event_to_dispatch);
   EventTarget* target = NULL;
   if (!event_to_dispatch->handled())
