public class JXRadioGroup<T>
extends JPanel

JXRadioGroup is a group of radio buttons that functions as a unit. It is similar in concept to a JComboBox in functionality, but can offer a better presentation for a small number of choices. JXRadioGroup should be used in preference to JComboBox when the number of choices is small (less than six) or the choices are verbose.

Notes:

1. Enabling and disabling the JXRadioGroup will enable/disable all of the child buttons inside the JXRadioGroup.
2. If the generic type parameter of JXRadioGroup is a subclass of AbstractButton, then the buttons will be added "as is" to the container. If the generic type is anything else, buttons will be created as JRadioButton objects, and the button text will be set by calling toString() on the value object.
3. Alternatively, if you want to configure the buttons individually, construct the JXRadioGroup normally, and then call getChildButton(int) or getChildButton(Object) and configure the buttons.

TODO back with a model (possibly reuse of extend ComboBoxModel
