> {{DirectoryTaxonomyWriter}} uses a cache to hold recently mapped labels / ordinals.  You can provide an impl when you create the class, or it will use a default impl.
>  
> I'd like to add a getter, {{DirectoryTaxonomyWriter.getCache}} to retrieve the cache it's using; this is helpful for getting diagnostics (how many cached labels, how much RAM used, etc.).
