// .NAME vtkMinMax - Finds the min, max, or sum of all of its input data
// attributes.
//
// .SECTION Description
// This filter lets the user choose from a set of operations and then runs
// that operation on all of the attribute data of its input(s). For example
// if MIN is requested, it finds the minimum values in all of its input data
// arrays. If this filter has multiple input data sets attached to its
// first input port, it will run the operation on each input data set in
// turn, producing a global minimum value over all the inputs. In parallel
// runs this filter REQUIRES ghost arrays to skip redundant
// information. The output of this filter will always be a single vtkPolyData
// that contains exactly one point and one cell (a VTK_VERTEX).
