详情----------Details----------
A biconnected graph is a connected graph that remains connected when any one of its vertices, and all the edges incident on this vertex, is removed and the graph remains connected. A biconnected component of a graph is a subgraph which is biconnected. An integer label is assigned to each edge to indicate which biconnected component it's in.
一个双连通图是一个连通图,保持连接时,任何一个顶点,这个顶点上的所有事件的边缘,被删除和图形保持连接。一个图的双连通分量,这是双连通子图。整数标签被分配到每边双连通的组成部分,它英寸
A vertex in a graph is called an articulation point if removing it increases the number of connected components.
图中的顶点,被称为一个关节点,如果删除它增加了连接的元件数量。

值----------Value----------
For biConnComp: a vector whose length is no. of biconnected components, each entry is a list of nodes that are on the same biconnected components.
biConnComp:一个向量,其长度是没有。双连通组件,每个条目是一个节点上相同的双连通元件的列表。
For articulationPoints: a vector of articulation points in the graph.
articulationPoints:向量图的衔接点。
