code: def addvFunc(self,solution,EndOfPrdvP):
          '''
          Creates the value function for this period and adds it to the solution.
  
          Parameters
          ----------
          solution : ConsumerSolution
              The solution to this single period problem, likely including the
              consumption function, marginal value function, etc.
          EndOfPrdvP : np.array
              Array of end-of-period marginal value of assets corresponding to the
              asset values in self.aNrmNow.
  
          Returns
          -------
          solution : ConsumerSolution
              The single period solution passed as an input, but now with the
              value function (defined over market resources m) as an attribute.
