页面进场离场的动画。

## 何时使用

- 从内容A到内容B的转变过程时能有效的吸引用户注意力，突出视觉中心，提高整体视觉效果。

- 小的信息元素排布或块状较多的情况下，根据一定的路径层次依次进场，区分维度层级，来凸显量级，使页面转场更加流畅和舒适，提高整体视觉效果和产品的质感。

## API

```jsx
<EnterAnimation>
  <div>依次进场</div>
  <div>依次进场</div>
  <div>依次进场</div>
  <div>依次进场</div>
</EnterAnimation>
```

```jsx
<EnterAnimation type="left" delay={2}>
  <div>
    <div enter-data>
      依次进场
    </div>
  </div>
  <div enter-data>依次进场</div>
  <div enter-data={{type: 'bottom'}}>依次进场，并修改动画效果</div>
  <div>没有动画</div>
</EnterAnimation>
```

如子节点有 `enter-data` 值，则只执行有 `enter-data` 的节点的动画，相反所有子节点上都没有 `enter-data` 值，则执行遍历dom下一级节点来执行动画。
