// .NAME vtkBoostConnectedComponents - Find the connected components of a graph
//
// .SECTION Description
// vtkBoostConnectedComponents discovers the connected regions of a vtkGraph.
// Each vertex is assigned a component ID in the vertex array "components".
// If the graph is undirected, this is the natural connected components
// of the graph.  If the graph is directed, this filter discovers the
// strongly connected components of the graph (i.e. the maximal sets of
// vertices where there is a directed path between any pair of vertices
// within each set).
