使用 `marks` 属性标注分段式滑块，使用 `value` / `defaultValue` 指定滑块位置。当 `included=false` 时，表明不同标记间为并列关系。当 `step=null` 时，Slider 的可选值仅有 `marks` 标出来的部分。

 en-US

Using `marks` property to mark a graduated slider, use `value` or `defaultValue` to specify the position of thumb.
When `included` is false, means that different thumbs are coordinative.
when `step` is null, users can only slide the thumbs onto marks.
