 * @Short_Description: Button displaying and allowing selection of a date.
 * @See_Also: #HildonPickerButton, #HildonTimeButton
 *
 * #HildonDateButton is a widget that shows a text label and a date, and allows
 * the user to select a different date. Visually, it's a button that, once clicked,
 * presents a #HildonPickerDialog containing a #HildonDateSelector. Once the user selects
 * a different date from the selector, this will be shown in the button.
