// .NAME vtkPeriodicFilter - A filter to produce mapped periodic
// multiblock dataset from a single block
//
// .SECTION Description:
// Generate periodic dataset by transforming points, vectors, tensors
// data arrays from an original data array.
// The generated dataset is of the same type than the input (float or double).
// This is an abstract class wich do not implement the actual transformation.
// Point coordinates are transformed, as well as all vectors (3-components) and
// tensors (9 components) in points and cell data arrays.
// The generated multiblock will have the same tree architecture than the input,
// except transformed leaves are replaced by a vtkMultipieceDataSet.
// Supported input leaf dataset type are: vtkPolyData, vtkStructuredGrid
// and vtkUnstructuredGrid. Other data objects are transformed using the
// transform filter (at a high cost!).
