[boost] [random] Speed up binomial and poisson distributions

Hi, I was wondering why the binomial distribution still isn't optimized for speed. If I look into the GSL as a comparison, they use much smarter and faster algorithms. As is, the bosst::random distributions are not usable for computational purposes to me, which is a pity since I very much like the approach using variate_generators and stuff... I would be happy to contribute some faster code, but I don't know how exactly I should proceed for that... should I contact the maintainer directly? Stephan
