> The facets module has multiple facet methods for counting flat and hierarchical fields,
and also a method for counting numeric ranges.  I'd like to also add a method that counts
unique numeric (long) values, designed to be used for fields that have only a few, typically
low valued, numbers across the index e.g. a "review" rating from 1 to 5.
