Perl implementation of the "Adapter" Design Pattern

The Class::Adapter class is intended as an abstract base class for creating any sort of class or object that follows the Adapter pattern.

The term Adapter refers to a "Design Pattern" of the same name, from the famous "Gang of Four" book "Design Patterns". Although their original implementation was designed for Java and similar single-inheritance strictly-typed language, the situation for which it applies is still valid.

An Adapter in this Perl sense of the term is when a class is created to achieve by composition (objects containing other object) something that can't be achieved by inheritance (sub-classing).

This is similar to the Decorator pattern, but is intended to be applied on a class-by-class basis, as opposed to being able to be applied one object at a time, as is the case with the Decorator pattern.
