How's this for MOL implementation?

      switch (order) {
      case 4:
      case 6: //1.25 ??
      case 7: //1.75 ??
        order = JmolAdapter.ORDER_AROMATIC;
        break;
      case 5:
        order = JmolAdapter.ORDER_PARTIAL12;
        break;
      }

The idea being that those 1.25/1.75 are probably aromatic. Or we could 
move 1.25 down to 1 and 1.75 up to 2?

      switch (order) {
      case 4:
        order = JmolAdapter.ORDER_AROMATIC;
        break;
      case 6: //1.25 ??
        order = 1;
        break;
      case 7: //1.75 ??
        order = 2;
        break;
      case 5:
        order = JmolAdapter.ORDER_PARTIAL12;
        break;
      }
