相对于vue1.0来说，vue2.0的动画变化还是挺大的，
在1.0中，直接在元素中加 transition ，后面跟上名字。
而在vue2.0中，需要把设置动画的元素、路由放在<transition name="fade"></transition>中，name就是动画名称。
在1.0时，css需要设置（动画名称以fade为例）.fade-transition .fade-enter .fade-leave
在2.0时，css设置大改，.fade-enter{} 元素初始状态 .fade-enter-active{} 元素最终状态 .fade-leave-active{} 元素离开的最终状态
在2.0中，依然可以与animate.css结合起来一起写动画，具体用法请看第三块代码
在2.0中，关于动画还为我们提供了一些事件，在下面第四段代码块
