// .NAME vtkTemporalRanges - Get the average, min, and max of fields over time.
//
// .SECTION Description
//
// This filter takes in any data set and computes the minimum, maximum, and
// average of the field talking into account all values over all time.  This
// filter is a bit like running both vtkDescriptiveStatistics and
// vtkTemporalStatistics.
//
// In addition to giving descriptive statistics for all field values over space
// and time, it will also give a single statistics over all blocks in a data
// set.
