command

   @cloud-fan I was thinking for these operators we would override 
verboseString(...) to print
   1. Filter -> Input, Condition
   2. Sort -> Input, Direction
   3. Limit -> Input, Number of rows
   
   Did you have different thoughts for what we want print as default for 
non-leaf operators ? We could just go with Input ? And for operators like 
`Project` etc, we could print both Input and output in the overridden 
implementation ? Let me know please ..
