Autoregressive HMM for HTS

This is an implementation of the autoregressive HMM built on top of HTS. It provides the ability to do embedded re-estimation and decision tree clustering for linear-Gaussian autoregressive output distributions.

An example of how to use this implementation is available (autoregressive HMM version of the HTS demo).
