-----------------------------------
    Description: 
Tuple0 is not cleanly integrated:
  - missing serialization/deserialization support in runtime
 - Tuple.getTupleClass(int arity) cannot handle arity zero, ie, cannot create 
an instance of Tuple0

Tuple0 is currently only used in Python API, but will be integrated into Storm 
compatibility, too.
