        <description>Sample aspect program to add getter methods for all member variables of
            a given class. The getter methods offers
                observability over an internal variable of a target class. 
        <p /> This aspect is implemented through two advices. The first advice modifies the
                comment of the target class to include a statement that the class has been modified by an aspect
                weaver. The second advice adds set of inline method definitions (inclusive of their comment).
                <p /> The name of the target class is
                <code>Derived</code>. The variables over which observability is given by the aspect program are 
                assumed to be defined in the target class itself (as opposed to one of its superclasses).
