// .NAME vtkTreeBFSIterator - breadth first search iterator through a vtkTree
//
// .SECTION Description
// vtkTreeBFSIterator performs a breadth first search traversal of a tree.
//
// After setting up the iterator, the normal mode of operation is to
// set up a <code>while(iter->HasNext())</code> loop, with the statement
// <code>vtkIdType vertex = iter->Next()</code> inside the loop.
//
// .SECTION Thanks
// Thanks to David Doria for submitting this class.
