;; Gibbs Sampling State - All distributions are DirichletMultinomial
;; type-assigns: map word string to tag state (integer)
;; tag-prior: prior distr over tag assignment
;; trans-distrs: map of tag => P(tag' | tag) distribution
;; emission-distrs: tag => P(word | tag) distribution, word=string representation
;; feat-distrs: tag => feat-type => P(feat-val | feat-type,tag) distribution
