 This interface should be implemented. Notes: When evaluating the value of this feature function, you should avoid calling hypo.GetPrevHypo(). If you need something from the "previous" hypothesis, you should store it in an FFState object which will be passed in as prev_state. If you don't do this, you will get in trouble.
