希望增加功能：拖动节点到相邻最近的节点时自动变更连线与之连接

[mtiger95]

Describe the feature you'd like to request

拖动节点A到相邻最近的节点B 时取消原来的连接，A和A的后面节点自动变更连线与这个最近的节点B连接。

Describe the solution you'd like

节点添加一个属性，比如connectToNearestNode，监听mouseMove事件，拖动时可以自动换连接上级。

Describe alternatives you've considered

或者拖动节点时，可以获取到节点坐标与周围节点的坐标，然后进行对比，开发者手动处理。
