AMViewAnimation—An NSView Category for Easy Animation

Today, I discovered the magic of NSViewAnimation. But I found it rather awkward to use on a quick basis, so I cooked up a lovely category on NSView that allows you to send it messages like fadeOut and animateToFrame in about 1/10th the characters. Sensible defaults are provided for everything, but you can change them if necessary. MIT License. Requires 10.4, of course. I hope this code proves useful. Please let me know if there are problems or suggestions.
