Subject: Several enhancements to gr-trellis and
gnuradio-examples/python/channel-coding: -Added fsm constructor for
generating FSM directly from the generator matrix of binary convolutional
codes. -Added functionality to fsm class to compute the best way to go from
any state to any other state (useful for termination) -Added soft-in-soft-out
(SISO) block for turbo processing -Added turbo decoding examples
