Incorrect local sum indices

[miha]

Diana writer produces incorect code for the included sum reducers, example:

CapeDouble SysCore2dSimpleESO::sum__85(CapeLong S4v_iz2) {
  CapeDouble res=0.0;
  for(CapeLong S4v_iz1=1;S4v_iz1<=S4v_nz1;S4v_iz1++)
    res+=(sum__86(S4v_iz1)*S4v_dz1);
  return res;
}

CapeDouble SysCore2dSimpleESO::sum__86(CapeLong S4v_iz1) {
  CapeDouble res=0.0;
  for(CapeLong S4v_iz2=1;S4v_iz2<=S4v_nz2;S4v_iz2++)
    res+=(S4v_i_a[S4v_iz1-1][S4v_iz2-1]*S4v_dz2);
  return res;
}
