DS_CA_RewardModel

   DS_CA_RewardModel constructor.

   Defines a reward function on discrete state and continuous
   action spaces, r(s,a).
   This is the type of reward functions is not used in the paper. It is
   the type of reward functions used in Spaan and Vlassis work (JAIR 2005)

   Note that the mixture defining this type of reward model is not
   normalized.

   Parameters
      S: Discrete state space.
      A: Continuous action space.
      r: A cell array of Gaussian mixture in 'a' (one for each state).
