/**
* Provides a way for toolbar buttons to be displayed when the toolbar itself doesn't have enough space for all buttons.
* The buttons that are cropped are displayed in a secondary toolbar, using a vertical layout.
* <p>
* To use this Feature replace:
* <code>
* frame.getContentPane().add(toolbar, BorderLayout.NORTH);
* </code>
* with
* <code>
* frame.getContentPane().add(MoreButton.wrapToolBar(toolBar), BorderLayout.NORTH);
* </code>
