JazzHands 2.0!

• Updated to work better with AutoLayout with new types of constraint animations
• Added a new IFTTTAnimatedPagingScrollViewController for quick-start AutoLayout-friendly animated paging scroll view animations.
• Added new keepView:onPage and keepView:onPages methods for much more simplicity in animating view positions on paging scrollviews, and much easier AutoLayout-friendly scrollviews.
• Updated Demo app to show how to create a fully AutoLayout-friendly paging animated scrollview, perfect for use with rotation or the new iOS9 Split Screen multitasking.
• Changed to simpler syntax for adding keyframes
• Updated to animate CGFloat times, to simplify keyframe times and work more smoothly on Retina displays.
• Switched from a pre-generated array of interpolated animation values to interpolating at any point between keyframes on demand, for faster animation creation and far fewer allocations when adding keyframes.
• Replaced IFTTTAngleAnimation with IFTTTRotationAnimation, which takes degrees instead of radians.
• Fixed Transform animations to work together. Now IFTTTScaleAnimation, IFTTTRotationAnimation, and IFTTTTranslationAnimation can all be used on the same view without conflicting.
• Increased unit test coverage.
• Made IFTTTAnimation easy to subclass with your own custom animation types (see MyCustomAnimation in the Demo app for an example of how easy this is).
• Added Interpolatable protocol to define how to interpolate between values of different types.
