    Doodle methods
    
    MAJOR UNRESOLVED ISSUES
    
    just like top-level event handlers and methods
    when dealing with a Notebook
    how do we want these kinds of methods to work with a SplitterBackground?
    if the event handlers and methods such as openFile are defined in the
    top-level parent then they will be found, but rather than references
    such as self.components.bufOff they would have to make specific
    references to the child such as self.win3.components.bufOff

    this makes sense from the standpoint that the associated menus
    also have to be specified in the top-level Background resource
    but it would seem to reduce reusability
    
    so could we and should we bind and dispatch events such that
    a child could add menus and menu items from its resource
    during the initLayout call or something like that?
    depending on the focus context, events would be directed
    at the appropriate child.
    i'm not even sure that is doable.
    
    needless to say the containers introduced with Notebook
    and SplitterBackground are making me worry about PythonCard
    becoming even more of a confusing hack job than it already is.
