[boost] [algorithm] Adding suffix automata, suffix array

Hello. I implemented Aho-Corasick to Boost.Algorithm. It's very useful algorithm, but i think that there are more useful algorithms, like suffix automata and suffix array. They can solve a lot of specific task on sequences of values: searching subsequences, count number of different subsequence, etc. Can i start work on it? ----- Best regards, Alexander Zaitsev.
