getBaseClassIndex creates an instance of the base class at every call,
getClassIndex just returns a number. Not good. Janek, what it the
boost::serialization solution of that?

from Indexable.hpp


    public: virtual int& getBaseClassIndex(int depth)            \
    {                                    \
        static boost::scoped_ptr<BaseClass> baseClass(new BaseClass);    \
        if(depth == 1)                            \
            return baseClass->getClassIndex();            \
        else                                \
            return baseClass->getBaseClassIndex(--depth);        \
    }
