Guideline is part of UI debug helper tools. Example usage can be as below, as it adds lines using autolayouts it is expected target view should be added to its superview.
```
let label = UILabel()
...
...
// Creates guidelines set to be displayed
let guidelines: UIView.Guideline = [.leading, .firstBaseline, .bottom]

// Shows guideline on label
label.showGuide(guideline: guidelines)
```
