Documentation

Flag variables for each state indicating whether the states emissions are tied to another state. Groups of tied states are represented by their tie group leader (the lowest numbered member of the group).

tied_to[s] == kUntied : s is not a tied state

tied_to[s] == s : s is a tie group leader

tied_to[t] == s : t is tied to state s

Note: tied_to != NULL iff (model_type & kTiedEmissions) == 1
