Serpent encryption algorithm

/*
* The Serpent algorithm's authors: Ross Anderson, Eli Biham and Lars Knudsen
* More information about Serpent at: http://www.cl.cam.ac.uk/~rja14/serpent.html
*
* Dag Arne Osvik found a way to express Serpent S-Boxes as boolean functions and
* Dr B. R. Gladman used this to implement the algorithm.
* BestCrypt Volume Encryption Serpent code is based on Dr B. R. Gladman implementation.
