[boost] [math] Contribution and TODO-list implementation.

Hello. I'm russian student. My department is Applied Math. I need to make my magister work and I would like to relate it with Boost.Math development. I think this work could be something like implementation of tasks mentioned in TODO-list. New feature development may take a long time. In the best case, I would be glad to take job and reviewer for it. If anyone has an idea - I'm ready to take serious and big job for 1,5 years. Thanks.
