Title: Added current progress property

Hello Pop,

Thanks for sharing this great library! I added a current progress property that you can use to see the current state of an animation. For my purposes, this is used to chain animations via a delegate based on whether or not they've completed a certain percentage of their animation.

In general, I think it is a useful value to retrieve from an animation.

Best,

Logan
