// .NAME vtkArrayExtentsList - Stores a collection of vtkArrayExtents objects.
//
// .SECTION Description
// vtkArrayExtentsList provides storage for a collection of vtkArrayExtents
// instances. Constructors are provided for creating collections
// containing one, two, three, or four slices. To work with larger
// numbers of slices, use the default constructor, the SetCount() method,
// and operator[].
//
// vtkArrayExtentsList is most commonly used with the vtkInterpolate()
// function, which is used to computed weighted sums of vtkArray slices.
//
// .SECTION See Also
// vtkArray, vtkExtents
//
// .SECTION Thanks
// Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National
// Laboratories.
