UITableView extension that enabled to insert cell from bottom of tableView.

## Concept

It is difficult to fill a tableview content from bottom.
So, ReverseExtension rotate both of UITableView and UITableViewCell like this images.

<img src="./Images/tableview1.png" width="21%">
<img src="./Images/tableview2.png" width="35%">
<img src="./Images/tableview3.png" width="21%">
<img src="./Images/tableview4.png" width="21%">

If you implement those in ViewController, it will have been fat.
So, escaping those implementation to `re` namespace property, and hiding those complex implementation.
In addition, you can rollback to normal behaviour, only removing `re` namespace.

## Example

```swift
import UIKit
import ReverseExtension

class ViewController: UIViewController {
    @IBOutlet weak var tableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.re.dataSource = self
        tableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")

        //You can apply reverse effect only set delegate.
        tableView.re.delegate = self
        tableView.re.scrollViewDidReachTop = { scrollView in
            print("scrollViewDidReachTop")
        }
        tableView.re.scrollViewDidReachBottom = { scrollView in
            print("scrollViewDidReachBottom")
        }
    }
}

extension ViewController: UITableViewDelegate {
    //ReverseExtension also supports handling UITableViewDelegate.
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        print("scrollView.contentOffset.y =", scrollView.contentOffset.y)
    }
}
```
