> I tried to combine these two and there were several issues:
> * It's ... really tricky to manage the two different
> FacetAccumulators across that N FacetCollectors that DrillSideways
> creates ... to fix this I added a new MultiFacetsAccumulator that
> switches for you.
> * There was still one place in DS/DDQ that wasn't properly handling
> a non-Term drill-down.
> * There was a bug in the "collector method" for DrillSideways
> whereby if a given segment had no hits, it was skipped, which is
> incorrect because it must still be visited to tally up the
> sideways counts.
> * Separately I noticed that DrillSideways was doing too much work:
> it would count up drill-down counts *and* drill-sideways counts
> against the same dim (but then discard the drill-down counts in
> the end).
