 * @class Ext.calendar.DayView

 * <p>Unlike other calendar views, is not actually a subclass of {@link Ext.calendar.CalendarView CalendarView}.
 * Instead it is a {@link Ext.Container Container} subclass that internally creates and manages the layouts of
 * a {@link Ext.calendar.DayHeaderView DayHeaderView} and a {@link Ext.calendar.DayBodyView DayBodyView}. As such
 * DayView accepts any config values that are valid for DayHeaderView and DayBodyView and passes those through
 * to the contained views. It also supports the interface required of any calendar view and in turn calls methods
 * on the contained views as necessary.</p>
 * @constructor
 * @param {Object} config The config object
