/***** calendar
* AUTHOR
* Garth Smedley
*
* REQUIRED INCLUDES
* <script type="application/x-javascript" src="chrome://global/content/strres.js"/>
* <script type="application/x-javascript" src="chrome://calendar/content/calendarEvent.js"/>
*
* NOTES
* Code for the oe-calendar.
*
* What is in this file:
* - Global variables and functions - Called directly from the XUL
* - Several classes:
* CalendarWindow - Owns the 3 subviews, keeps track of the selection etc.
* CalendarView - Super class for three views
* MonthView
* WeekView
* DayView
* - Unifinder functions - fill in content of the unifinder.
*
* IMPLEMENTATION NOTES
*
* WARNING - We currently use CalendarEvent objects in what will be an unsafe way
* when the datasource changes. We assume that there is exactly one instance of CalendarEvent for
* each unique event. We will probably have to switch to using the calendar event id
* property instead of the object. G.S. April 2001.
