Unused TypeInformation parameter in DeltaIteration constructor

Hey,

the DeltaIteration constructor has a TypeInformation parameter that is not
used:

DeltaIteration(ExecutionEnvironment context, TypeInformation<ST> type,
DataSet<ST> solutionSet, DataSet<WT> workset, Keys<ST> keys, int
maxIterations) {
initialSolutionSet = solutionSet;
initialWorkset = workset;
solutionSetPlaceholder = new SolutionSetPlaceHolder<ST>(context,
solutionSet.getType(), this);
worksetPlaceholder = new WorksetPlaceHolder<WT>(context, workset.getType());
this.keys = keys;
this.maxIterations = maxIterations;
}

The solution set and workset types are set separately, so I guess this is a
leftover parameter because of some copy-paste? Or was it meant to be used
somewhere else?

Cheers,
V.
