// .NAME vtkBoostBiconnectedComponents - Find the biconnected components of a graph
//
// .SECTION Description
// The biconnected components of a graph are maximal regions of the graph where
// the removal of any single vertex from the region will not disconnect the
// graph. Every edge belongs to exactly one biconnected component. The
// biconnected component of each edge is given in the edge array named
// "biconnected component". The biconnected component of each vertex is also
// given in the vertex array named "biconnected component". Cut vertices (or
// articulation points) belong to multiple biconnected components, and break
// the graph apart if removed. These are indicated by assigning a component
// value of -1. To get the biconnected components that a cut vertex belongs
// to, traverse its edge list and collect the distinct component ids for its
// incident edges.
