// .NAME vtkTransferAttributes - transfer data from a graph representation
// to a tree representation using direct mapping or pedigree ids.
//
// .SECTION Description
// The filter requires
// both a vtkGraph and vtkTree as input. The tree vertices must be a
// superset of the graph vertices. A common example is when the graph vertices
// correspond to the leaves of the tree, but the internal vertices of the tree
// represent groupings of graph vertices. The algorithm matches the vertices
// using the array "PedigreeId". The user may alternately set the
// DirectMapping flag to indicate that the two structures must have directly
// corresponding offsets (i.e. node i in the graph must correspond to node i in
// the tree).
//
