[IMP-dev] SingletonFunctor

Daniel - why is it better using: IMP_NEW(core::Transform, tsm,(t)); for(Particles::iterator it = ps.begin(); it != ps.end();it++) { tsm->apply(*it); } instead of: std::for_each(ps.begin(),ps.end(),SingletonFunctor(new IMP::core::Transform(t)));

I saw you changed it in domino .

thanks, Keren.
