Count with zero columns #75

Closed sadikovi closed 7 years ago

sadikovi commented 7 years ago

Currently, when we run count, we use single column unix_secs to return as part of Array[Object]. This PR updates scan planner and default source, so we run count on 0 columns, each InternalRow is empty.
