Angelscript demo of exposing trivial classes (very quick 1hr project)

I need an experienced C++ code who has a lot of experience using AngelScript. I have just come accross AngelScript (yesterday), and want to use it in one of my projects. I have already exposed constants and enumerations from an existing C++ library to AngelScript. I need help from an expert to show me how to do the following: 1. expose a POD C++ class a value type and use it in a script. This class must be garbage collected by the AngelScript GC. 2. expose a more complicated C++ class as a reference class. This class must 'expose' an object handle type to the script so that object handles can be used in the script. Once again, this class must be exposed in a way so that it can garbage collected by the GC. 3. Show how an object can be exposed via the application interface so that it is created by the application that embeds the script and the object is available and usable in the script BUT cannot be destroyed in the script. Please see the attached header file for the lightweight classes that need to be exposed to the AngelScript engine. As I mentioned before for a coder already experienced with AngelScript, the required code can be completed and tested within an hour.
