Add SegueManager/R.swift example

[tomlokhorst]

R.swift has been designed to work well with my SegueManager library.

Although your post is titled "Swift Asset Code Generators" (which SegueManager isn't), it also talks about segues.
So I thought I'd show an example of how R.swift and SegueManager work together to allow you to perform a segue with a (typed) closure:

performSegue(R.segue.detailViewController.imageView) { segue in
  segue.destinationViewController.imageToShow = R.image.lolwut()
}

As mentioned in your post, at the moment R.swift doesn't restrict segues from being performed on the wrong view controller. But this is being worked on: mac-cain13/R.swift.Library#2

@tomlokhorst Thanks for the update! I'll take some time this weekend to update my blog post to mention SegueManager and merge these changes.
