Fix sc simple maker
Very interesting bad feature of CaloDDE->IdentifierHash. I wonder if this happens in other places (What do you think @pavol?? Maybe there are many places where I might have done this wrongly). It looks like caloDDE->IdentifierHash returns a hash within the SubCalo, instead of doing so within the whole calorimeter. @lbaltes (I hope I got the right one), got the point (Thanks a lot) and I propose here a fix for the specific algorithm she was talking about. This is probably the reason why we have some issues yet to be understood in the HEC and FCAL superCells.
