Elena's functional hyperloglog module

Project description

Allows you to take intersection of arbitrarily many hyperloglogs.

hll = HyperLogLog(0.01) # 0.01 is % accuracy hll.add(1) # can add objects of any type hll2 = HyperLogLog(0.01) hll3 = HyperLogLog(0.01)

hll.intersectoin([hll2, hll3]) # returns cardinality of intersection set NOTE THAT IN ORDER TO TAKE INTERSECTION ALL SETS MUST BE THE SAME SIZE or in other words, MUST HAVE THE SAME % ACCURACY
