The EaseInOutBase class is the base class that provide easing capability. The EaseInOutBase class defines easing as consisting of two phases: the acceleration, or ease in phase, followed by the deceleration, or ease out phase. The default behavior of this class returns a linear interpolation for both easing phases. You can create a subclass of EaseInOutBase to get more interesting behavior.
