About Parameter Training for a Directed Graph

[puyuanliu]

Could you add an example to use your package to do Parameter Training on a Directed Graph?
It is mentioned in your documentation that we should use fg. baumWelch ( factorList , numRestarts , numSteps ); to train the parameter. But how do we import the data to the training? What should be placed in the factor List if I am training a Dynamic Bayesian Net?
