> ConstantObjectInspectors seem to do the right thing for UDFs, but don't work yet for UDAFs, in part of the complex getEvaluator path which converts back and forth between TypeInfo and ObjectInspectors.  We should add an interface so that UDAFs can operate entirely on ObjectInspectors and expose constantness to these UDAFs.
