SÉLECTEUR DE DATES MULTIPLES

package demo;
/*
 * Demo.java
 * 
 * This demo shows you how to use a MultiDateChooser
 * and a MultiDateButton.
 * 
 * It displays a MultiDateChooser on the frame.
 * The Button "Show selected Dates" displays the selections made
 * on that date chooser.
 * 
 * The Button "Datechooser Dialog" is a MultiDateButton.
 * It displays a Dialog with another MultiDateChooser.
 * The selections made there are displayed immediately in an OptionPane
 * that pops up via the "DateSelectionListener" which is implemented 
 * directly by this "Demo" class.
 * 
 * The Button "Clear All" clears the selections in both "MultiDateChooser"s
 * (the one in the frame and the one in the dialog).
