Returns a T:WinRTXamlToolkit.Automation.Peers.CalendarAutomationPeer for use by the Silverlight automation infrastructure.
This method creates a new CalendarAutomationPeer instance if one has not been created for the control instance; otherwise, it returns the CalendarAutomationPeer previously created.
Classes that participate in the Silverlight automation infrastructure must implement this method to return a class-specific derived class of AutomationPeer that reports information for automation behavior.
