|OpennessRestorer (TreeViewItem &)|
This handy class takes a copy of a TreeViewItem's openness when you create it, and restores that openness state when its destructor is called.
This can very handy when you're refreshing sub-items - e.g.
OpennessRestorer openness (*this); // saves the openness state here..
// add a bunch of sub-items here which may or may not be the same as the ones that
// were previously there
// ..and at this point, the old openness is restored, so any items that haven't
// changed will have their old openness retained.
