[ublas] vector::back()

[slyilmaz]

It would be nice to have this useful, nice little member...

T& back() {
 return *rbegin();
}

and

const T& back() const {
 return *rbegin();
}

I take ownership to watch this issue. However, don't expect it to be implemented soon.

I do agree with slyilmaz. uBLAS vector could be more similar with standard STL vector, so that an easier interoperability could be in place.
