Define the widget layout for given style. If layoutspec is
        omitted, return the layout specification for given style.

        layoutspec is expected to be a list or an object different than
        None that evaluates to False if you want to "turn off" that style.
        If it is a list (or tuple, or something else), each item should be
        a tuple where the first item is the layout name and the second item
        should have the format described below:

        LAYOUTS

            A layout can contain the value None, if takes no options, or
            a dict of options specifying how to arrange the element.
            The layout mechanism uses a simplified version of the pack
            geometry manager: given an initial cavity, each element is
            allocated a parcel. Valid options/values are:

                side: whichside
                    Specifies which side of the cavity to place the
                    element; one of top, right, bottom or left. If
                    omitted, the element occupies the entire cavity.

                sticky: nswe
                    Specifies where the element is placed inside its
                    allocated parcel.

                children: [sublayout... ]
                    Specifies a list of elements to place inside the
                    element. Each element is a tuple (or other sequence)
                    where the first item is the layout name, and the other
                    is a LAYOUT.
