-/**
- * A standalone view decorator adding over-scroll with a smooth bounce-back effect to (potentially) any view -
- * provided that an appropriate {@link IOverScrollDecoratorAdapter} implementation exists / can be written
- * for that view type (e.g. {@link RecyclerViewOverScrollDecorAdapter}).
- *
- * <p>Design-wise, being a standalone class, this decorator powerfully provides the ability to add
- * the over-scroll effect over any view without adjusting the view's implementation. In essence, this
- * eliminates the need to repeatedly implement the effect per each view type (list-view,
- * recycler-view, image-view, etc.). Therefore, using it is highly recommended compared to other
- * more intrusive solutions.</p>
- *
- * <p>Note that this class is abstract, having {@link HorizontalOverScrollBounceEffectDecorator} and
- * {@link VerticalOverScrollBounceEffectDecorator} providing concrete implementations that are
- * view-orientation specific.</p>
- *
- * <hr width="97%"/>
- * <h2>Implementation Notes</h2>
- *
- * <p>At it's core, the class simply registers itself as a touch-listener over the decorated view and
- * intercepts touch events as needed.</p>
- *
- * <p>Internally, it delegates the over-scrolling calculations onto 3 state-based classes:
- * <ol>
- *     <li><b>Idle state</b> - monitors view state and touch events to intercept over-scrolling initiation
- *     (in which case it hands control over to the Over-scrolling state).</li>
- *     <li><b>Over-scrolling state</b> - handles motion events to apply the over-scroll effect as users
- *     interact with the view.</li>
- *     <li><b>Bounce-back state</b> - runs the bounce-back animation, all-the-while blocking all
- *     touch events till the animation completes (in which case it hands control back to the idle
- *     state).</li>
- * </ol>
