基于jquery.jsPlumb编写拓扑图
要求：实现公司组织结构拓扑关系，可展开，可收拢；动态数据展示；叶子节点可点击；
实现办法：
1 国内还有一个插件也比较简单，但是该插件只能全部展开，并不能收拢，放弃了该办法；
2 最后选择了这个插件，因为相关资料很少，所以每步都是自己摸索出来的；
对数据的要求：因为该插件的每个节点都是一个具有独立不同id的div模块，所以json数据要求有一个id属性，并且所有的id都要不一样；
实现的原理：
1 先定位所有的节点（这个还简单点，只要依次遍历数据就行）；
2 添加拓扑关系；（这个地方比较复杂，尤其是点击节点时，其他节点收缩，直接点展开，里面的循环量特别大，几乎都是在一个大循环里面套用了很多的子循环）
