/**
 * This class is the primary class for accessibility support via the
 * Accessibility ToolKit (ATK).  Objects which are instances of
 * #AtkObject (or instances of AtkObject-derived types) are queried
 * for properties which relate basic (and generic) properties of a UI
 * component such as name and description.  Instances of #AtkObject
 * may also be queried as to whether they implement other ATK
 * interfaces (e.g. #AtkAction, #AtkComponent, etc.), as appropriate
 * to the role which a given UI component plays in a user interface.
 * 
 * All UI components in an application which provide useful
 * information or services to the user must provide corresponding
 * #AtkObject instances on request (in GTK+, for instance, usually on
 * a call to #gtk_widget_get_accessible ()), either via ATK support
 * built into the toolkit for the widget class or ancestor class, or
 * in the case of custom widgets, if the inherited #AtkObject
 * implementation is insufficient, via instances of a new #AtkObject
 * subclass.
 * 
 * See also: #AtkObjectFactory, #AtkRegistry.  (GTK+ users see also
 * #GtkAccessible).
