/** A single radio button performs the same basic function as a Gtk::CheckButton, as its position in the object hierarchy reflects. It is only when multiple radio buttons are grouped together that they become a different user interface component in their own right.
 * Every radio button is a member of some group of radio buttons. When one is selected, all other radio buttons in the same group are deselected. A Gtk::RadioButton gives the user a choice from many options.
 * After constructing the first RadioButton in a group, use get_group() and provide this Group to the constructors ot the other RadioButtons in the same group.
 * To remove a Gtk::RadioButton from one group and make it part of a new one, use set_group().
