      Description

      Today, when you index a FacetField with path foo/bar, we index two drill down terms onto the document: foo and foo/bar.

      But I suspect some users (like me!) don't need to drilldown just on foo (effectively "find all documents that have any value for this facet dimension"), so I added an option to FacetsConfig to let you specify per-dimension whether you need to drill down (defaults to true, matching current behavior).

      I also added hashCode and equals to the LongRange and DoubleRange classes in facets module, and improved CheckIndex a bit to print the total %deletions across the index.
