// Created by Markn 11/1/96
// Defines a class that will encapsulate lists of attributes.
//
// NOTE: It is derived from the MFC class CMapPtrToPtr.  This breaks rules to do with winoil/kernel cross-over
// but it doesn't make the old system any worse, which insidently, uses CMapPtrToPtr directly.
// This new class will allow common functions to be put in one place, and will also aid reimplementation
// if this becomes necessary.
