/**
* Skein interface. The Skein specification defines three main
* functions, called Skein-256, Skein-512 and Skein-1024, which can be
* further parameterized with an output length. For the SHA-3
* competition, Skein-512 is used for output sizes of 224, 256, 384 and
* 512 bits; this is what this code implements. Thus, we hereafter call
* Skein-224, Skein-256, Skein-384 and Skein-512 what the Skein
* specification defines as Skein-512-224, Skein-512-256, Skein-512-384
* and Skein-512-512, respectively.
