// OpenCalendar
// The OpenCalendar function can be used as a shortcut to the actual window.open statement that 
// ultimately must be issued.  OpenCalendar includes a rudimentary popup blocker detection
// system that unfortunately won't always work because of a wide variety of methods employed
// to block popup windows.  You may want to inform your guests that popup blockers should be
// disabled for your site for proper functioning.
