+/*
+This test demonstrates director classes when the types are classes.
+Shown are virtual function calls which use classes passed by:
+  - Value
+  - Reference
+  - Pointer
+as both parameters and return values.
+The test also demonstrates directors used with:
+  - method overloading
+  - default parameters
+Note: Methods with default parameters that call up from C++ cannot call
+the overloaded C# methods, see DefaultParms method.
+
+Expected output if PrintDebug enabled:
+------------ Start ------------
+Base - Val(444.555)
+Base - Ref(444.555)
+Base - Ptr(444.555)
+Base - FullyOverloaded(int 10)

+Base - SemiOverloaded(int -678)
+Base - SemiOverloaded(bool 1)
+Base - DefaultParms(10, 2.2)
+Base - DefaultParms(10, 1.1)

+  This test program shows a C# class CSharpDerived inheriting from Base. Three types of classes are created
+  and the virtual methods called to demonstrate:
+  1) Wide variety of primitive types
+  2) Calling methods with zero, one or more parameters
+  3) Director methods that are not overridden in C#
+  4) Director classes that are not overridden at all in C#, ie non-director behaviour is as expected for director classes
+  5) Inheritance hierarchy using director methods
+  6) Return types working as well as parameters
+
+  The Caller class is a tester class, which calls the virtual functions from C++.
