*
* Description:
* This file defines the model state data structure. The state
* data structure contains indices of model parameters associated
* with the state and it contains adjacency lists of prior states
* and next states.
*
* The states defined in this structure are in the context of
* an utterance HMM built to model a whole utterance. Hence it
* is built as a network of subword HMM's.
