  7.  **  IntegerExample.c -- Integer class Example.
  8.  **
  9.  **  This is a simple example testing some of the capabilities of the
  10.  **  Integer gadget class.
  11.  **
  12.  **  This code opens a window and then creates 2 Integer gadgets which
  13.  **  are subsequently attached to the window's gadget list.  One uses
  14.  **  arrows, one does not.  Notice that you can tab cycle between them.
