great code.
SerpentEngineBase.cs
Partially optimised Serpent S Box boolean functions derived
using a recursive descent analyser but without a full search
of all subtrees. This set of S boxes is the result of work
by Sam Simpson and Brian Gladman using the spare time on a
cluster of high capacity servers to search for S boxes with
this customised search engine. There are now an average of
15.375 terms    per S box.
