// 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.
