Based on the idea of iOS Navigation Controller
###How to use:
####1) Your controller should be a CODBaseViewController Class
@interface YOURCUSTOM_SUBCLASS : CODBaseViewController
####2) Set up your App Delegate
self.navigationController = [[CODNavigationController alloc]initWithRootViewController:YOURCONTROLLER_INSTANCE];
self.window.contentViewController = self.navigationController;
####3) How to pop/push
//Push
[self.navigationController pushViewController:YOUR_NEW_VC animated:ANIMATE];
//Pop
[self.navigationController popViewControllerAnimated:ANIMATE];
####TODO list: Push/Pop: Resize window to the previous/next view controller (now is fixed)
