object Hash128 extends Serializable

This gives default hashes using Murmur128 with a seed of 12345678 (for no good reason, but it should not be changed lest we break serialized HLLs)

    This serializes the string into UTF-8, then hashes.

    This serializes the string into UTF-8, then hashes. This is different than the UTF-16 based approach in Murmur128.apply(CharSequence), but has been more commonly used in HLL.
