First of all, thanks for making this project available, it's very
interesting. I have two (hopefully quick) questions:
Is there any primer for how to use it? I'm trying to figure it out by
looking at the unit tests but there seems to be several ways to use it and
I'm a little lost in that regard.
Secondly, is there any way to find the actual population size using the
HyperLogLog estimator? I'd like to not only see the cardinality but also
the population size. I can always subclass it and record the count
separately (it'd be a simple counter, count++ type of thing), but it seems
like there's some more direct method that I'm missing.
