// .NAME vtkTreeIterator - Abstract class for iterator over a vtkTree.
//
// .SECTION Description
// The base class for tree iterators vtkTreeBFSIterator and vtkTreeDFSIterator.
//
// 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 See Also
// vtkTreeBFSIterator vtkTreeDFSIterator

// The start vertex of the traversal.
// The tree iterator will only iterate over the subtree rooted at vertex.
// If not set (or set to a negative value), starts at the root of the tree.

// Return true when all vertices have been visited.
