// .NAME vtkBoostBreadthFirstSearch - Boost breadth_first_search on a vtkGraph
//
// .SECTION Description
//
// This vtk class uses the Boost breadth_first_search
// generic algorithm to perform a breadth first search from a given
// a 'source' vertex on the input graph (a vtkGraph).
//
// .SECTION See Also
// vtkGraph vtkGraphToBoostAdapter
