*        <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.
