A category that makes UINavigationController can pop to any specified UIViewController in it's stack.

Usage

How can we pop back to [aViewController]?

----------------------
| bViewController    |
----------------------
| aViewController    | <-- pop back
----------------------
| rootViewController |
----------------------

Import header file in [aViewController] and [cViewController]:

#import "UINavigationController+UUCustomRoot.h"

Implement isCustomRootViewController method in [aViewController]:
