Message:

trunk: just realized, that polimorphism again is the evil part of classes.
Classes, that derive say from PNode and Element2D force that Element2D is registered after PNode, which means, that Element2D is interpretet as being derived from PNode in my implmentational idea…
hmm… now go for some new approach, this cannot and will not be the end of this…
