> 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.
