+xxHash is an extremely fast non-cryptographic hash algorithm, running at RAM
+speed limits.  It is proposed in two flavors, 32 and 64 bits. It successfully
+completes the SMHasher test suite which evaluates collision, dispersion and
+randomness qualities of hash functions. Code is highly portable, and hashes are
+identical on all platforms (little / big endian).
