// .NAME vtkPeriodicDataArray - Map native an Array into an angulat
// periodic array
//
// .SECTION Description
// Map an array into a periodic array. Data from the original array aare
// rotated (on the fly) by the specified angle along the specified axis
// around the specified point. Lookup is not implemented.
// Creating the array is virtually free, accessing a tuple require some
// computation.
