Prediction

   Belief evolution under the given action. 
 
   Updates a belief applying action 'a'.
   Parameters:
     AM: The action model to use.
     s: The hidden state. We also update it to use it in simulations.
        Note, however, that this state is never accesible by the planner
        (only the beliefs are).
     b: The belief to update.
     a: The action to apply
     Sp: Space where the belief is defined (used to bound the belief and
         the hidden state if necessary).
   Outputs:
     sOut: The updated hidden state.
     bOut: The updated belief.
