| The Power class defines the easing functionality using a polynomial expression. |
| Easing consists of two phases: the acceleration, or ease in phase, |
| followed by the deceleration, or ease out phase. |
| The rate of acceleration and deceleration is based on |
| the <code>exponent</code> property. |
| The higher the value of the <code>exponent</code> property, |
| the greater the acceleration and deceleration. |
| Use the <code>easeInFraction</code> property to specify the percentage |
| of an animation accelerating. |
