* @class vtkExtractDataOverTime
* @brief extract point data from a time sequence for
* a specified point id.
*
* 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.
