/**
    @file IDentifierIncludes.h
    @brief Definition of macros for the class-hierarchy and the factory.

    Every class needs the RegisterObject(class) macro in its constructor. If the class is an interface
    or the BaseObject itself, it needs the macro RegisterRootObject(class) instead.

    To allow the object being created through the factory, use the CreateFactory(class) macro outside
    the of the class implementation, so it gets executed before main().
