> Currently the grouping module has many collector classes with a lot of different options
per class. I think it would be a good idea to have a GroupUtil (Or another name?) convenience
class. I think this could be a builder, because of the many options (sort,sortWithinGroup,groupOffset,groupCount
and more) and implementations (term/dv/function) grouping has.
