/**
 * <p> An interval action is an action that takes place within a certain period of time. <br/>
 * It has an start time, and a finish time. The finish time is the parameter<br/>
 * duration plus the start time.</p>
 *
 * <p>These CCActionInterval actions have some interesting properties, like:<br/>
 * - They can run normally (default)  <br/>
 * - They can run reversed with the reverse method   <br/>
 * - They can run with the time altered with the Accelerate, AccelDeccel and Speed actions. </p>
 *
 * <p>For example, you can simulate a Ping Pong effect running the action normally and<br/>
 * then running it again in Reverse mode. </p>
