The Exponential class defines three easing functions to implement
motion with Flex effect classes, where the motion is defined by
an exponentially decaying sine wave.

public static function easeIn(t:Number, b:Number, c:Number, d:Number):Number
Language Version : ActionScript 3.0
Runtime Versions : Flash Player 9, AIR 1.1
The easeIn() method starts motion slowly,
and then accelerates motion as it executes.
Parameters
t :Number b :Number c :Number d :Number
Returns Number — Number corresponding to the position of the component.
public static function easeInOut(t:Number, b:Number, c:Number, d:Number):Number
Language Version : ActionScript 3.0
Runtime Versions : Flash Player 9, AIR 1.1
The easeInOut() method combines the motion
of the easeIn() and easeOut() methods
to start the motion slowly, accelerate motion, then decelerate.
Parameters
t :Number b :Number c :Number d :Number
Returns Number — Number corresponding to the position of the component.
public static function easeOut(t:Number, b:Number, c:Number, d:Number):Number
Language Version : ActionScript 3.0
Runtime Versions : Flash Player 9, AIR 1.1
The easeOut() method starts motion fast,
and then decelerates motion as it executes.
Parameters
t :Number b :Number c :Number d :Number
Returns Number — Number corresponding to the position of the component.
