Overhaul implementation; do not use gmm::phi(). This gives serious speedup, as

high-dimensional matrix inverses are not being calculated. The previous calls
to gmm::phi() would invert a diagonal matrix without being able to assume that
the matrix was diagonal. This explains the very very poor benchmarking results
for nbc in mlpack.
