/**
* @class vtkArrayExtentsList
* @brief Stores a collection of vtkArrayExtents objects.
*
*
* 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.
*
* @sa
* vtkArray, vtkExtents
*
* @par Thanks:
* Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National
* Laboratories.
