1. just addressed Matei's comments by encapsulating event processing logic
into functions in DAGScheduler
2. fixed a bug, where in the original implementation, if the event is not
StopScheduler, submitWaitingStages is called after processed each event...I
missed that, and now, I called this function in handle***
3. refactor GettingResultEvent, as I found that the task parameter is
actually not used....
