二、实现思路
1、设置面板容器元素的left属性值，触发下一轮轮播，将left - viewSize(大于等于面板宽度)，当前为最后一轮时，将当前显示的面板子元素的兄弟元素设置相对定位，并设置相应的位置，支持下一轮轮播循环；触发上一轮轮播，将left + viewSize，当前为首轮时，同理将当前显示的面板子元素的兄弟元素设置相对定位，并设置相应的位置，支持下上一轮轮播循环；2、如果当前面板显示的元素只有一个时，允许有触发器，监听mouseenter事件，并显示对应的面板子元素；
3、激活面板子元素所对应的当前触发器的状态，这一部分在动画完成后实现，当前触发器的className为固定trigger-active ks-active，当然也可以自行配置；
4、当鼠标移动在整个外围容器中时，将清除自动轮播的定时器，离开时重新执行定时器，支持自动轮播，自动轮播的延迟时间为可配置项delay，其他配置项interval为自动轮播
的间隔时间，duration为动画时间，autoplay默认为false。

});PS: 实现的过程操作均在动画完成之后执行的，就是用户必须在轮播完后，进行下一次的上下轮播，这也算是我的实现瓶劲，望高手多多指教
