// .NAME vtkBoostExtractLargestComponent - Extract the largest connected
// component of a graph
//
// .SECTION Description
// vtkBoostExtractLargestComponent finds the largest connected region of a
// vtkGraph. For directed graphs, this returns the largest biconnected component.
// See vtkBoostConnectedComponents for details.
