** ChoosserExample.c -- chooser class example.
**
** This is a simple example testing some of the capabilities of the
** chooser gadget class.
**
** This opens a window with chooser gadget. We will usse ClassAct.lib's
** ChooserLables() and FreeChooserLabels() utility functions to create the
** item labels.
