 * @class   vtkArrayRename
 * @brief   Rename data arrays.
 *
 *  This class takes any vtkDataObject as input, shallow copies its content to
 *  the output and renames its data arrays.
 *
 *  For each attributes type, array name should be unique.
 *
 *  Supported attributes type are the following: POINT, CELL, FIELD, VERTEX, EDGE and ROW.
