/** The base object class for the Accessibility Toolkit API.
 * This class is the primary class for accessibility support via the Accessibility ToolKit (ATK). Objects which are
 * instances of Atk::Object (or instances of Atk::Object-derived types) are queried for properties which relate basic
 * (and generic) properties of a UI component such as name and description. Instances of Atk::Object may also be queried
 * as to whether they implement other ATK interfaces (e.g. Atk::Action, Atk::Component, 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
 * Atk::Object 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 Atk::Object implementation is insufficient, via instances of a new Atk::Object subclass.
