Subject: [PATCH] Parent and Child relationship is working. If the parent is
 closed its children will be closed too. But the child's children not (in this
 version).

The parent knows about its children in self.children list variable. The child knows about its parent in self.parent variable. When a child is closed the its id will be removed its parent (self.children) list variable.
