 *	Helper macros to implement safe pointer attachments
 *
 *	When another object obtains a pointer to your class it can then
 *	call Attach(pointer&) to register it's interest.
 *
 *	When the server object is deleted all attached pointers will be
 *	safely NULLed.
 *
 *	To use:
 *		1.	Add DECLARE_PTR_ATTACHMENT(ClassName) to the operations
 *			section of your header file
 *
 *		2.	Add IMPLEMENT_PTR_ATTACHMENT(ClassName) to your
 *			implementation file
 *
 *		3.	Add a call to NullAttachedPointers() to the class destructor
 *
 *	These macros are provided to avoid the need for a "mix-in" class
 *	implementing this capability
