[ublas] [bindings][traits] traits::vector_storage / traits::matrix_storage does not work with ublas::unbounded_array

Hello,

I have tested the latest numeric bindings, but have met compilation errors
when
I use ublas vector/matrix classes with default storage array
(ublas::unbounded_array).
It seems that traits::vector_storage / traits::matrix_storage  fails because
of the missing
traits class for unbounded_array. It works if I use the std::vector for a
storage array
instead of unbounded_array:

#include <boost/numeric/bindings/traits/vector_traits.hpp>
#include <boost/numeric/bindings/traits/std_vector.hpp>
#include <boost/numeric/bindings/traits/ublas_vector.hpp>

namespace traits = boost::numeric::bindings::traits;
namespace ublas = boost::numeric::ublas;
int main()
{
        ublas::vector<double, std::vector<double> > v(10);
        double *vp = traits::vector_storage(v); // <- OK
        ublas::vector<double, ublas::unbounded_array<double> >  w(10);
        double *wp = traits::vector_storage(w); // <- Error
        return 0;
}

The error messages I got is as follows (using g++ 4.3.3):

./boost/numeric/bindings/traits/ublas_vector.hpp: In static member function
‘static typename boost::numeric::bindings::traits::default_vector_traits<V,

Could you kindly fix this problem?
