Class ``ptr_set``
-----------------

A ``ptr_set<T>`` is a pointer container that uses an underlying ``std::set<void*>``
to store the pointers.

- associative_ptr_container_
- ptr_set_adapter_

                                        Key,
                                        std::set<void*,
                                        void_ptr_indirect_fun<Compare,Key>,Allocator>,
                                        CloneAllocator
                                    >
            {
                // see references
                
            }; //  class 'ptr_set'
        
        } // namespace 'boost'  

**Remarks:**

- Using ``nullable<T>`` as ``Key`` is meaningless and not allowed
