/** A Tween animates numeric properties of objects. It uses different transition functions
* to give the animations various styles.
*
* <p>The primary use of this class is to do standard animations like movement, fading,
* rotation, etc. But there are no limits on what to animate; as long as the property you want
* to animate is numeric (<code>int, uint, Number</code>), the tween can handle it. For a list
* of available Transition types, look at the "Transitions" class.</p>
*
* <p>Here is an example of a tween that moves an object to the right, rotates it, and
* fades it out:</p>
*
* <listing>
* tween:Tween = new Tween(object, 2.0, Transitions.EASE_IN_OUT);
* tween.animate("x", object.x + 50);
* tween.animate("rotation", deg2rad(45));
* tween.fadeTo(0); // equivalent to 'animate("alpha", 0)'
* Starling.juggler.add(tween);</listing>
*
* <p>Note that the object is added to a juggler at the end of this sample. That's because a
* tween will only be executed if its "advanceTime" method is executed regularly - the
* juggler will do that for you, and will remove the tween when it is finished.</p>
*
* @see Juggler
* @see Transitions

* <p>Some property types are handled in a special way:</p>
* <ul>
* <li>If the property contains the string <code>color</code> or <code>Color</code>,
* it will be treated as an unsigned integer with a color value
* (e.g. <code>0xff0000</code> for red). Each color channel will be animated
* individually.</li>
* <li>The same happens if you append the string <code>#rgb</code> to the name.</li>
* <li>If you append <code>#rad</code>, the property is treated as an angle in radians,
* making sure it always uses the shortest possible arc for the rotation.</li>
* <li>The string <code>#deg</code> does the same for angles in degrees.</li>
* </ul>
