CS_DA_RewardModel

   CS_DA_RewardModel constructor.

   Defines a reward function on continuous state and discrete
   action spaces, r(s,a).
   This is the type of reward functions defined at the end of section 5.1
   in the paper.

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

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