// .NAME vtkArraySort - Controls sorting of sparse array coordinates.
//
// .SECTION Description
// vtkArraySort stores an ordered set of dimensions along which the
// values stored in a sparse array should be sorted.
//
// Convenience constructors are provided for specifying one, two, and
// three dimensions. To sort along more than three dimensions, use the
// default constructor, SetDimensions(), and operator[] to assign each
// dimension to be sorted.
//
// .SECTION See Also
// vtkSparseArray
//
// .SECTION Thanks
// Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National
// Laboratories.
