// purpose	Define structure and type definition for the links of a doubly
//		linked list stack/queue node and anchor, and pointers.
//
// usage	This struct must be the first member of an application struct
//		defined to hold data to be placed in the list/stack/queue.
//		The application can then do operations on the first member,
//		or define higher level versions of these functions that call
//		these functions, and work with those definitions directly.
