Awesome work, Boris.

I'm very happy to see a small chapter on ptr_container.
It's good that you compare it with container<unique_ptr<T>>.

Comment 1: I would prefer examples with unique_ptr to use make_unique.

Comment 2: The are two major other difference betweeen ptr_vector<T> and

A. No element can be null(by default), this can never be guranteed with
vector<unique_ptr<T>>, as you can just move en element out or push_back
a null.

B. Automatic cloning: ptr_containers can be copy'ed, performing a deep
clone of the elements.

kind regards
