Review comment:

At first , I think for a TransformStep there could be one sink or a sink
list. So I add a implicit method，and the argument can be WriteStep or
List[WriteStep].
But now,I think for the result table or dataframe of a transformStep, there
could be only one WriteStep( one sink can sink to different places and we
don't need different output logic). So i want to chuange the interface to
**Option[WriteStep]** .
Is that ok ?
