##### 效果2

以及自定义节点的内容
#### 使用说明

1.  引入模块
```
    layui.config({
        base: './lib/layui_exts/',
    }).extend({
        flowNode: "flowNode",
    }).use(['flowNode'], function () {
           let flowNode = layui.flowNode
    });
```
2.  在指定元素内输出页面
```
    let flowNodeObj = flowNode.render({
        el:'#flow_nodes',//要输出到的目标元素
        data:[],//节点数据
        nodeContent: function(node){
            //参数为当前节点数据
            return node.title
        },//自定义节点内容
    });
```

3.  刷新
```
    flowNodeObj.reload(nodes)
```
#### 数据结构说明
```
[
    {"id":1,
                "pid":0,//父级节点id
                "title":"开始",//节点标题，可自定义
                "type":1,//节点类型：1开始节点，2结束节点（舍弃），3普通节点，4收敛节点
                "children":[],//子节点，决定节点的分支情况，每个子节点结构与此相同
                "convergent":{},//收敛节点，决定了多分支的合并效果，一个节点只能包含一个收敛节点，结构与此相同
    }
]
```
#### 数据结构大体思路
重要一点，将收敛节点父级设置与分支开始节点的父级一致，其他后续补充...

#### 数据结构示例
