Update README.md 

Change the terminology. It's actually scrolling the views, not modifying the bounds.

# TLYShyNavBar
This component helps you mimick the navigation bar expansion/contraction that you see in the facebook, instagram and other apps. Not only that, but with the ability to add an additional extension that expands/contracts as well!

## A Deeper Look
The above example, while small, is complete! It makes the navigation bar enriched with humbility, that it will start getting out of the way when the scroll view starts scrolling. But, you may want to do more than that!

#### ACCESS THE MANAGER OF SHYNESS

It is a simple concept. Say we dragged down by 100 px, and the nav bar was contracted. The navigation bar would take 64 px of that to expand, and then pass the residual 36 px to the next node (extension view) to calculate its offset. The same goes for contracting, but it starts from the last node, all the way up to the navigation bar.
*Note:* Even though there might be an illusion that the views are expanding and contracting, it's really just a translation (scrolling) of the views. There might be an advantage to actually resizing the bounds, so the extension view doesn't appear behind the navigation bar, for example, so that approach might be explored in the future.
## Remarks
There are downsides in making this component as easy to use as it is. If you have read the how it works section carefully, you'd realize that trying to configure the the `shyNavBarManager` before it is included in the `UINavigationController` heirarchy, will break the component, since within the component, we cannot find the navigation bar, and an assert is triggered:
