class  KnownStateTrainer 
Provide trainers which estimate parameters based on training sequences. These should be used to 'train' a Markov Model prior to actually using it to decode state paths. When supplied training sequences and a model to work from, these classes will estimate paramters of the model. This aims to estimate two parameters: * a_{kl}  the number of times there is a transition from k to l in the training data. * e_{k}(b)  the number of emissions of the state b from the letter k in the training data.
