+wyhash and wyrand are the ideal 64-bit hash function and PRNG respectively:
+
+solid: wyhash passed SMHasher, wyrand passed BigCrush, practrand.
+
+portable: 64-bit/32-bit system, big/little endian.
+
+fastest: Efficient on 64-bit machines, especially for short keys.
+
+simplest: In the sense of code size.}
