 * calendar components and expects records of type {@link Ext.calendar.EventRecord}.</p>
 * <p>Note that this template would not normally be used directly. Instead you would use the {@link Ext.calendar.DayViewTemplate}
 * that internally creates an instance of this template along with a {@link Ext.calendar.DayHeaderTemplate}.</p>
