This interface contains the required methods (if any) from the protocol defined by MonoTouch.StoreKit.SKRequestDelegate.

If you create objects that implement this interface, the implementation methods will automatically be exported to Objective-C with the matching signature from the method defined in the MonoTouch.StoreKit.SKRequestDelegate protocol.

Optional methods (if any) are provided by the MonoTouch.StoreKit.SKRequestDelegate_Extensions class as extension methods to the interface, allowing you to invoke any optional methods on the protocol.
