/**
* @brief Base class for constructing a @a safe unordered container type
* that tracks iterators that reference it.
*
* The class template %_Safe_unordered_container simplifies the
* construction of @a safe unordered containers that track the iterators
* that reference the container, so that the iterators are notified of
* changes in the container that may affect their operation, e.g., if
* the container invalidates its iterators or is destructed. This class
* template may only be used by deriving from it and passing the name
* of the derived class as its template parameter via the curiously
* recurring template pattern. The derived class must have @c
* iterator and @c const_iterator types that are instantiations of
* class template _Safe_iterator for this container and @c local_iterator
* and @c const_local_iterator types that are instantiations of class
* template _Safe_local_iterator for this container. Iterators will
* then be tracked automatically.
