// .NAME vtkPExtractArraysOverTime - extract point or cell data over time (parallel)
// .SECTION Description
// vtkPExtractArraysOverTime is a parallelized version of
// vtkExtractArraysOverTime.
// vtkExtractArraysOverTime extract point or cell data given a selection. For
// every cell or point extracted, vtkExtractArraysOverTime create a vtkTable
// that is placed in an appropriately named block in an output multi-block
// dataset. For global-id based selections or location based selections, it's
// possible that over time the cell/point moves across processes. This filter
// ensures that such extractions spread across processes are combined correctly
// into a single vtkTable.
// This filter produces a valid output on the root node alone, all other nodes,
// simply have empty multi-block dataset with number of blocks matching the root
// (to ensure that all processes have the same structure).
