示例1: benchmark
/// benchmark() runs a simple benchmark by letting Stockfish analyze a set
/// of positions for a given limit each. There are five parameters; the
/// transposition table size, the number of search threads that should
/// be used, the limit value spent for each position (optional, default is
/// depth 12), an optional file name where to look for positions in fen
/// format (defaults are the positions defined above) and the type of the
/// limit value: depth (default), time in secs or number of nodes.
