to create the equivalent of the, now obsolete, const_matrix_row_type, I now
create a numerics::row< const Matrix >. But using its operator()(int i), a
get an error of assinging a const double to a double&. AFAICT, this is
because the row< const Matrix >::reference takes reference of the template
argument which ends up being a Matrix::reference. Should'nt a traits class
handle the `const Matrix` argument and make the reference const ?
