    This Cucapp tests the following:
        • CPAnimationContext -setCompletionHandler: is called and the end value is correct when the frame of a view is animated.
            Tested for a vanilla view (no drawing, no layout), a view with custom drawing, with custom layout, with both.
        • CPAnimationContext CPView special keyPaths CPAnimationTriggerOrderIn and CPAnimationTriggerOrderOut.
            Checks that adding or removing the animator to/from the superview does not throw an error and the superview final value is correct.
