/** Utilizes a tween to animate the target object over a certain time. Internally, this
* method uses a tween instance (taken from an object pool) that is added to the
* juggler right away. This method provides a convenient alternative for creating
* and adding a tween manually.
*
* <p>Fill 'properties' with key-value pairs that describe both the
* tween and the animation target. Here is an example:</p>
*
* <pre>
* juggler.tween(object, 2.0, {
* transition: Transitions.EASE_IN_OUT,
* delay: 20, // -> tween.delay = 20
* x: 50 // -> tween.animate("x", 50)
* });
* </pre>
