The main feature of the iconbar.py program is the placing of an icon on the
icon bar. This is achieved by the following lines:
sprites = app.Sprite()
icon = app.IconBar((sprites, 'file_ffd', ''))
A sprite area object is set up by the use of the Sprite class. This object is
made to refer to the system sprite area as a result of the system method.
It is then possible to add an icon to the icon bar by instantiating an IconBar
object using the sprite area object and asking for the "file_ffd" data filetype sprite.
Note that the icon will by default appear on the right hand side of the icon bar along
with the other applications.
