/**
* This class implements the Skein core function when used with a
* 256-bit internal state ("Skein-256" in the Skein specification
* terminology). This class is not currently used, since the recommended
* parameters for the SHA-3 competition call for a 512-bit internal
* state ("Skein-512") for all output sizes (224, 256, 384 and 512
* bits).
