/**
 * Radio choice which creates two values for a boolean-backed model.
 * <p>
 * This control serves as an alternative to checkboxes, especially in
 * bootstrap's horizontal forms. See <a href=
 * "http://ux.stackexchange.com/questions/22532/laying-out-checkboxes-in-forms"
 * >this UX Stackexchange question</a> for more information and supporting
 * ideas.
 * <p>
 * You can localize the labels for true/false options by providing localization
 * properties for:
 * <ol>
 * <li>BooleanRadioChoice.TRUE</li>
 * <li>BooleanRadioChoice.FALSE</li>
 * </ol>
