Comment:
r11143 adds `mlpack::math::RandomSeed(const size_t)` which can be used to
set the random seed. The final thing to be done, then, is to add a --seed
option to each program which uses randomnity. I've not added a call to
`RandomSeed()` to the `CLI` constructor and I think it's better that way.
All the necessary programs (GMM, HMM, K-Means, RADICAL) now have that
option. As far as I know, our code is compatible across all relatively
recent versions of Boost.Random (I went as far back as 1.39.0 and as far
forward as 1.48.0).
