+// Simple class for doing key value path animation on a target.
+// The key value path of target will be set to the currentValue
+// (not the currentProgress) of the animation.
+// Defaults to NSAnimationNonblocking as opposed to NSAnimationBlocking
+// because in our experience most use cases don't want blocking animations.
+// KeyPath of target must represent a CGFloat value.
