Viterbi algorithm uses backtracking to find the most probable state
sequence, but nowhere in the implementation of HMM::Prediction() can I
find the backtracking stage. The array StateSeq is set only in the forward
pass. This is obviously not correct because stateSeq[0] is determined
without even seeing the later observations.
