This class provides an intelligent interface to Foundation's key-value coding capabilities (see NSKeyValueCoding in Chapter 2). The main purpose of this class is to provide an interface for objects to determine the properties and characteristics of a class. NSClassDescription is an abstract class, upon which Foundation implements the concrete subclass NSScriptClassDescription.
