Summary: Stream summarizer and cardinality estimator

Description:
A Java library for summarizing data in streams for which it is
infeasible to store all events. More specifically, there are classes
for estimating: cardinality (i.e. counting things); set membership;
top-k elements and frequency. One particularly useful feature is that
cardinality estimators with compatible configurations may be safely
merged.
