                                         _AbstractParentedElement

Known Subclasses:: _MultiParentedElement, _ParentedElement

An abstract base class for (multi)parented element tree Elements.

Whenever a new child is added, _setparent is called, which should update that child's parent pointer to point at self.
Whenever a child is removed, _delparent is called, which should remove the child's parent pointer to self.
