// .NAME vtkExtractArraysOverTime - extract point or cell data over time
// .SECTION Description
// vtkExtractArraysOverTime extracts point or cell data of one point or
// cell over time. The output is a 1D rectilinear grid where the
// XCoordinates correspond to time (the same array is also copied to
// a point array named Time or TimeData (if Time exists in the input).
// When extracting point data, the input point coordinates are copied
// to a point array named Point Coordinates or Points (if Point Coordinates
// exists in the input).
// This algorithm does not produce a TIME_STEPS or TIME_RANGE information
// because it works across time.
// .Section Caveat
// vtkExtractArraysOverTime puts a vtkOnePieceExtentTranslator in the
// output during RequestInformation(). As a result, the same whole
// extented is produced independent of the piece request.
// This algorithm works only with source that produce TIME_STEPS().
// Continuous time range is not yet supported.
