README

        
Download the first frame of an animated gif, instead of the full thing.

example usages:

```swift

	func example() {

		let url = NSBundle.mainBundle().URLForResource("puppy", withExtension: "gif")!

		let operation = CQIntroductoryGIFFrameOperation(URL: url)

		// note: `completionBlock` is also available from NSOperation, although it

		// works based off of KVO states, and will take an extra runloop or two to fire.

		operation.target = self

		operation.action = "gifProcessed:"

		NSOperationQueue.mainQueue().addOperation(operation)

	}

	@objc func gifProcessed(operation: CQIntroductoryGIFFrameOperation) {

		if let image = operation.introductoryFrameImageData {

			print("we have a still image of the first frame of an animated gif!")

		}

	}

```

or

```swift

	func example() {

		let url = NSBundle.mainBundle().URLForResource("puppy", withExtension: "gif")!

		let operation = CQIntroductoryGIFFrameOperation(URL: url)

		operation.completionBlock = {

			if let image = operation.introductoryFrameImageData {

				print("we have a still image of the first frame of an animated gif!")

			}

		}

		NSOperationQueue.mainQueue().addOperation(operation)

	}

```
