PointerVector's copy constructor/assignment can potentially introduce object slicing.

[Dimi1010]

The current implementation of PointerVector<T> contains a copy constructor/assignment that does a deep copy of all elements.

The issue is that the element wise copy is done via T* x = new T(*elemIt) which would slice off any polymorphic types held in the vector via a pointer to a base type.

A potential twofold solution can be:

• Removal of the copy constructor/assignment of PointerVector<T>, making the class similar to a collection of std::unique_ptr.
• Adding a SFINAE enabled clone() method, allowing the copy of the vector provided the base class T provides a clone() method.
