more consistent variable names
TMP: vectorize _forward_probability
hmm: update_outputs flag for train_unsupervised
show baseline in BW demo
vectorize _backward_probability
vectorize Baum-Welch step
more vectorized calculations for Baum-Welch
consistently use self._output_logprob
use logsumexp2
Remove mentions of nltk_speed for now
