SYNScrollViewObserverEffects

SYNScrollViewObserverEffects is a set of classes that observe the content offset of one scrollview and generate different effects. The primary goal was to be unobtrussive and able to react to changes in a scroll view without having to be the delegate. Effects included:

1. Parallax scrolling to show depth of UI.
2. Enlarge a view when the scrollview is pulled down too far.
3. An image blur of a UIImageView image.
4. An effect to show and hide the a Navigation bar based on scrolling.

Note: The blur effect in this library is requires iOS 7+. All else should work with at least iOS 6.
