// .NAME vtkExtractDataOverTime - extract point data from a time sequence for
// a specified point id.
// .SECTION Description
// This filter extracts the point data from a time sequence and specified index
// and creates an output of the same type as the input but with Points
// containing "number of time steps" points; the point and PointData
// corresponding to the PointIndex are extracted at each time step and added to
// the output. A PointData array is added called "Time" (or "TimeData" if
// there is already an array called "Time"), which is the time at each index.
