Test dojo.fx.reverse

This is a test for the dojo.Animation extension, dojox.fx.ext-dojo.reverse. To use, simply require dojox.fx.ext-dojo.reverse and a reverse() method will be added to all dojo.Animations.

dojox.fx.ext-dojo.reverse can be used at any time during the animation. It does not need to be called when it ends. It also reverses the easing — if dojo.fx.easing.quadIn is used, dojo.fx.easing.quadOut will be used when animating backwards.
