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)...`.
