+ * Layering: Layers are sorted into the Tree. e.g:
+ * the roor is in the lowest Layer, the leaves in the highest (of each branche)
+ * the first child of each node is in the lowest layer of all children, the last in the highest
+ * -> the tree is sorted on insertion of a new Child: @see Element2D::addChild2D()
