 r952 In addition to the obvious value and label properties the user can also control
the visual appearance of a slice. By modifying the visual appearance also means that
the user is overriding the default appearance set by the theme. Even if the theme is
changed users settings will persist.
To enable user interaction customization with the slices some basic signals
are provided about clicking and hovering.
