// Summary:
//     Class CXTPCalendarController provides a connection between a
//     CXTPCalendarControl object and a CXTPDatePickerControl object.
// Remarks:
//     A CXTPCalendarController object provides a synchronization
//     facilities between CXTPCalendarControl and CXTPDatePickerControl
//     controls. It works as a "glue" between both controls and
//     reflects changes on one of them to the corresponded changes on the
//     second one.
// See Also: CXTPCalendarControl, CXTPDatePickerControl

	//-----------------------------------------------------------------------
	// Summary:
	//     Constructs a CXTPCalendarController object.
	// Remarks:
	//     Construction of the CXTPCalendarController object defines
	//     a point of synchronization between CXTPCalendarControl and
	//     CXTPDatePickerControl controls. It can be constructed both
	//     in the same scope with controls which would provide us with
	//     full live objects time synchronization, and in the local scope
	//     for short time synchronization.
	//
	// Example:
	// <code>
	// Declare a local CXTPCalendarController object.
	// CXTPCalendarController myCalendarController;
	//
	// // Assigns CXTPCalendarControl instance to the object.
	// myCalendarController.SetCalendar(&m_wndCalendar);
	//
	// // Assigns CXTPDatePickerControl instance to the object.
	// myCalendarController.SetDatePicker(&m_wndDatePicker);
	// </code>
