/*
This program demonstrates several aspects of SCF usage:
- Dynamic class loading/unloading (Dog and Worm classes)
- Always-static class linkage (Frog class)
- Object-created-within-object (Worm::Split method)
- Run-time class registration with SCF kernel (no need for scf.cfg)
- Embedded interface (iName within iDog)
- Multiple interfaces (iFrog also supports iName)
