Implementation of a "Singleton" class

This is the "Class::Singleton" module. A Singleton describes an object class that can have only one instance in any system. An example of a Singleton might be a print spooler or system registry. This module implements a Singleton class from which other classes can be derived. By itself, the "Class::Singleton" module does very little other than manage the instantiation of a single object. In deriving a class from "Class::Singleton", your module will inherit the Singleton instantiation method and can implement whatever specific functionality is required. For a description and discussion of the Singleton class, see "Design Patterns", Gamma et al, Addison-Wesley, 1995, ISBN 0-201-63361-2. Author: Andy Wardley <abw@wardley.org>
