\brief Why did you implement different versions for each generic
\brief container type instead of using a template template

To support container serialization, each container has to be
implemented in an own overloaded version, because Microsoft
Visual Studio lacks template type parameter deduction for this
kind of declaration:
template <template <typename> class CONTAINER, typename T>
Archive& operator<<(const ObjectNamer<CONTAINER<T> >&);
To support this compiler as well, different operators for each
supported container type have been implemented.
