New main program that uses our new datatypes and objects.

1998-04-02  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* main.c: New main program that uses our new datatypes and
	objects.

	* calendar.c (calendar_load_from_vobject, calendar_load):
	Implement loading of vCalendar objects and vCalendar files.

	* calobj.c (ical_object_create_from_vobject): Implement loading of
	vCalendar event and todo objects.

	* timeutil.c (isodate_from_time_t): New function.

	* gnome-cal.c, gnome-cal.h: Implement a toplevel widget, derived
	from GnomeApp.  It holds all of the day views and arbitrates the
	display.
