Re: [BLAST_ANAWARE] v3 reconstruction unit convention

I would argue for adopting SI units everywhere as this is the standard.
The only problem I see is with GEANT which is not consistent which is of
course the reason for Aaron's choice.

But whatever is decided let me know and I will change my codes and the
parameter files to conform.
