> while simple {{type:range}} facets don't benefit from refinement, because 
> every shard returns the same set of buckets, some bugs currently exist when a 
> range facet contains sub facets that use refinement:
> # the optional {{other}} buckets (before/after/between) are not considered 
> during refinement
> # when using the {{include}} option: if {{edge}} is specified, then the 
> refinement of all range buckets mistakenly includes the lower bound of the 
> range, regardless of whether {{lower}} was specified.
> ----
> #1 occurs because {{FacetRangeMerger extends 
> FacetRequestSortedMerger<FacetRange>}} ... however {{FacetRangeMerger}} does 
> not override {{getRefinement(...)}} which means only 
> {{FacetRequestSortedMerger.buckets}} is evaluated and considered for 
> refinement. The additional, special purpose, {{FacetBucket}} instances 
> tracked in {{FacetRangeMerger}} are never considered for refinement.
> #2 exists because of a mistaken in the implementation of {{refineBucket}} and 
> how it computes the {{start}} value.
