using standard viterbi block from trellis (enhancement)

[mattip]

Thanks for this package. I am trying to work through it, and am wondering why you chose to rewrite the viterbi_decoder rather than use one from the gnuradio trellis coding package. Could you take a look and see if it would make sense to use the standard Viterbi block? What parameters would I use?

Hi, the standard Viterbi code from Gnuradio was very slow and that is why I implemented my own one. There is an explanation here: http://yo3iiu.ro/blog/?p=1393

Now, I know that gnuradio gr-fec evolved in the last months so the viterbi implementation may be working as fast as need now. However, there is a chance that gr-dvbt will be included in gnuradio in the near future so that will solve the problem.
