Feature request - access to root xib view

[Gargo]

From your readme:

final class MyCustomWidget: UIView, NibOwnerLoadable {
  …
  required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    self.loadNibContent()
  }
}

The problem is I loose a link to xib root view and can access it via MyCustomWidget().subviews property only or by making a link to this view manually each time.

Why it is required? For example, I create a subview with labels which should be added to a view controller with a dark background. So I make subview's background dark in xib (to see light labels) and change this color back in runtime.
