OK I see. I think the code works OK though. It documents that you should
call the other constructor if you specify a custom indexFieldName for some
of the dimensions.
Currently if you index dimensions under different indexFieldNames, you
should initialize a FacetsCounts per indexFieldName. There's no way for the
default ctor of FastTaxonomyFacetCounts to determine which indexFieldName
to use as it doesn't know which dimensions you're going to ask to count.
Hope that helps.
