Acton常见的缓动动作

/**
 * Author:W
 * 节点的缓动动作：不可以单独存在，它只是用来“修饰”基础动作，可以修改基础动作的时间曲线，
 * 让动作有快入、缓入、快出等复杂的特效。只有时间间隔动作才支持缓动动作。常见缓动动作参照表如下：
 * 
 * cc.easeIn 创建easeIn缓动对象，由慢到快
 * cc.easeOut 创建easeOut缓动对象，由快到慢
 * cc.easeInOut 先由慢到快，再由快到慢
 * 
 * cc.easeExponentialIn
 * cc.easeExponentialOut
 * cc.easeExponentialInOut
 * 
 * cc.easeSineIn
 * cc.easeSineOut
 * cc.easeSineInOut
 * 
 * cc.easeElasticIn
 * cc.easeElasticOut
 * cc.easeElasticInOut
 * 
 * cc.easeBounceIn
 * cc.easeBounceOut
 * cc.easeBounceInOut
 * 
 * cc.easeBackIn
 * cc.easeBackOut
 * cc.easeBackInOut
 * 
 * cc.easeBezierAction
 * 
 * cc.easeQuadraticActionIn
 * cc.easeQuadraticActionOut
 * cc.easeQuadraticActionInOut
 * 
 * cc.easeQuarticActionIn
 * cc.easeQuarticActionOut
 * cc.easeQuarticActionInOut
 * 
 * cc.easeQuinticActionIn
 * cc.easeQuinticActionOut
 * cc.easeQuinticActionInOut
 * 
 * cc.easeCircleActionIn
 * cc.easeCircleActionOut
 * cc.easeCircleActionInOut
 * 
 * cc.easeCubicActionIn
 * cc.easeCubicActionOut
 * cc.easeCubicActionInOut
 *
