requires !is_array<ELEMENT_TYPE>::value && !is_pointer<ALLOC>::value;Return a shared_ptr object referring to and managing a new ELEMENT_TYPE object. The specified basicAllocator will be used to supply a single contiguous region of memory holding the returned shared pointer's internal representation and the new ELEMENT_TYPE object, which is initialized by calling allocator_traits<ALLOC>::construct passing basicAllocator, an ELEMENT_TYPE * pointer to space for the new shared object, and the specified arguments std::forward<ARGS>(args)....
