/**
 * This test program shows a D class DDerived inheriting from Base.
 *
 * Three types of classes are created and the virtual methods called to
 * demonstrate:
 *  - Wide variety of primitive types
 *  - Calling methods with zero, one or more parameters
 *  - Director methods that are not overridden in D
 *  - Director classes that are not overridden at all in D, i.e. non-director
 *    behaviour is as expected for director classes
 *  - Inheritance hierarchy using director methods
 *  - Return types working as well as parameters
 *
 * The Caller class is a tester class which calls the virtual functions from C++.
