* Transition-based rewards are parsed using the existing (Deterministic)SparseTransitionsParser.
* State-based rewards are parsed using a new SparseStateRewardParser that parses lines consisting of a state and an associated reward.
* The Dtmc class now stores the two reward models.
* The DtmcParser class now parses up to one transition-based and one state-based reward file. They may, however, be omitted in which case the respective reward model is set to null.
