 * quickly.  This script should not be seen as part of the calendar.  It just
 * shows you what one can do with the calendar, while in the same time
 * providing a quick and simple method for setting it up.  If you need
 * exhaustive customization of the calendar creation process feel free to
 * modify this code to suit your needs (this is recommended and much better
 * than modifying calendar.js itself).
