Starting with Flex 4.0, Apache recommends that you use the spark.effects.easing.Power class as an alternative to this class.
The Spark effects provided as of Flex 4 use classes which implement the
IEaser interface instead of the easing functions in classes like Cubic for
the earlier Flex 3 effects. To achieve the same functionality of Cubic,
create a Power instance with an exponent of 3 and set the
easeInFraction appropriately to get the desired result.
The Cubic class defines three easing functions to implement
motion with Flex effect classes. The acceleration of motion for a Cubic easing
equation is greater than for a Quadratic easing equation.

The easeInOut() method combines the motion
of the easeIn() and easeOut() methods
to start the motion from zero velocity, accelerates motion, then decelerates
back to a zero velocity.

The easeOut() method starts motion fast,
and then decelerates motion to a zero velocity as it executes.
