Aza Raskin 5e96413c12 This is a feel update.
+ Created a new easing function called "tabcandyBounce" (which will soon be all the rage in the underground dance clubs fo Europe).
+ tabcandyBounce is the kind of easing function that gentle overshoots the ends and then bounces back, giving a human feel.
+ tabcandyBounce feels faster than it actually is :)
+ The new easing function is now used for most animations.
