Added Uber Mode which adds class methods and strongly typed return values.

See the updated example project for how category methods and strong types work.

Here's a quick example:
```objective-c
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:CGTAMainStoryboardName bundle:nil];
CGTADetailViewController *detailViewController = [storyboard instantiateViewControllerWithIdentifier:CGTAMainStoryboardDetailViewControllerIdentifier];
```

becomes

```objective-c
CGTADetailViewController *detailViewController = [CGTAMainStoryboard instantiateDetailViewController];
```

Segues, collection view cells, and table view cells are scoped to the view controller.
