Create a shared pointer that takes over the management of the modifiable object previously managed by the specified `autoPtr` to the (template parameter) type `CONVERTIBLE_TYPE`, and that refers to `(ELEMENT_TYPE *)autoPtr.get()`. `delete(autoPtr.release())` will be called to destroy the shared object when all references have been released. Optionally specify a `basicAllocator` used to allocate and deallocate the internal representation of the shared pointer. If `basicAllocator` is 0, the currently installed default allocator is used. If `CONVERTIBLE_TYPE *` is not implicitly convertible to `ELEMENT_TYPE *`, then a compiler diagnostic will be emitted indicating the error.
