RDF::Base::Metaclass
This is a class for objects that inherits from more than one special class. See Para::Frame::Resource/find_class.
Those metaclasses inherits from this and the other classes.
If a class wants to reimplement a method existing
RDF::Base::Resource, that method must be specially implemented
here, because only the first method will be found and if we inherit from
two classes and only one of them implements say desig, it may be
the other class that gets tried first and then it will use
RDF::Base::Resource/desig.
We may introduce class priority for determining which class is tried first.
