/**
 * @class   vtkBoostConnectedComponents
 * @brief   Find the connected components of a graph
 *
 *
 * vtkBoostConnectedComponents discovers the connected regions of a vtkGraph.
 * Each vertex is assigned a component ID in the vertex array "component".
 * 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).
