  // Actual code
  //
  // This code exemplifies multiple Monte Carlo solvers, each calling this qoi routine. 
  // In this simple example, only node 0 in each sub-environment does the job even though 
  // there might be more than one node per sub-environment.
  // In a more realistic situation, if the user is asking for multiple nodes per sub-
  // environment, then the model code in the qoi routine might really demand more than one
  // node. Here we use 'env.subRank()' only. A realistic application might want to use 
  // either 'env.subComm()' or 'env.subComm().Comm()'.
