HyperLogLog++ cardinality estimation algorithm

hllpp is an implementation of the HyperLogLog++ cardinality estimation algorithm in go. It optimizes for memory usage over CPU usage. It implements all the HyperLogLog optimizations introduced in the HyperLogLog++ paper (http://goo.gl/Z5Sqgu). Some notable features include:

 * Marshaling so you can serialize to your datastore,
 * Extra space savings by only using 5 bits per register when possible,
 * Built-in non-streaming murmur3 implementation for fast hashing of input
   data.

This is the dev package.
