要深拷贝的值
2. [customizer] (Function)
这个函数定制返回的拷贝值
### 返回值 (\*)
返回拷贝后的值
### 示例
```
function customizer(value) {
if (_.isElement(value)) {
return value.cloneNode(true);
}
}
var el = _.cloneDeep(document.body, customizer);
console.log(el === document.body);
// => false
console.log(el.nodeName);
// => BODY
console.log(el.childNodes.length);
// => 20
```
