/* \file This file uses libkeccak.h, the stand-alone implementation
 * of the keccak hash algorithm. The reason to use this rather than
 * std::hash, is that std::hash is explicitly not guaranteed to be stable
 * across implementations (compilers, platforms, ...).
 * We insist on having something stable across platforms,
 * such that your hashes which you may use for random seeds
 * are the same, such that the physics you simulate is identical
 * across platforms. */
