* The Toolbars class is a container of toolbars.
* It provides accessors to each Toolbar and to the LayoutBox.
*
* Each GUI frontend should provide toolbar and layout boxes by derivation
* from the LayoutBox and Toolbar pure abstract classes.
*
* The Toolbars class has no knowledge at all of the details of each
* frontend's implementation, which requires that each frontend should
* provide a 'make_toolbar' function, signature below.
