Create a managed pointer having a target object referenced by the specified ptr, owning the managed object *ptr, and having a deleter that will call delete ptr to destroy the managed object when invoked (e.g., when this managed pointer object is destroyed), unless 0 == ptr, in which case create an empty managed pointer. The deleter will invoke the destructor of MANAGED_TYPE rather than the destructor of TARGET_TYPE. This constructor will not compile unless MANAGED_TYPE * is convertible to TARGET_TYPE *. Note that this behavior allows ManagedPtr to be defined for void pointers, and to call the correct destructor for the managed object, even if the destructor for TARGET_TYPE is not declared as virtual. The behavior is undefined unless the managed object (if any) can be destroyed by delete, or if the lifetime of the managed object is already managed by another object.
