[mlpack] [mlpack/mlpack] Implement multidimensional discrete distribution (#830)

[Ryan Curtin]

Hi there @MikeLing, thanks for the contribution.  Unfortunately I'm not totally sure what this overload does since there are no comments.

Ideally, for multidimensional discrete distribution support, the API shouldn't change, it should just be a generalization.  Note that now, when you call `DiscreteDistribution::Probability()`, the parameter `const arma::vec& observation` must be a one-dimensional vector.  The idea is to generalize this, so that a discrete distribution can have many dimensions.

The distribution should have zero correlation across dimensions, so if I have the vector "a,b" then P(a,b) = P(a)P(b).
