Baum-Welch-Algorithm for parameter reestimation (training) in a StateLabelHMM. Scaled version for multiple sequences, alpha and beta matrices are allocated with stat_matrix_d_alloc New parameters set directly in hmm (no storage of previous values!). For reference see: Rabiner, L.R.: "`A Tutorial on Hidden {Markov} Models and Selected Applications in Speech Recognition"', Proceedings of the IEEE, 77, no 2, 1989, pp 257--285
Parameters:
- mo initial model
sq - training sequences
Returns:
0/-1 success/error
