Hi Namik,

What should I do to drop the usage > of boost in Sparse benchmark? The replacement for this uses a sparse matrix type obtained from a nesting of std::vector and std::map, i.e. std::vector< std::map<size_t, T> > I'll update the respective benchmark for you when I'm back in Vienna later this week.
