  //  computed in a previous time step)?
  //  3 - do we need to compute this interactionBlock? A interactionBlock is
  //  to be computed if interi and interj are in IndexSet1 AND if interi and
  //  interj have common DynamicalSystems.
  //
  // The possible cases are:
  //
  //  - If 1 and 2 are true then it does nothing. 3 is not checked.
  //  - If 1 == true, 2 == false, 3 == false, it does nothing.
  //  - If 1 == true, 2 == false, 3 == true, it computes the
  //    interactionBlock.
  //  - If 1==false, 2 is not checked, and the interactionBlock is
  //    computed if 3==true.
