// .NAME vtkInformationVector - Store zero or more vtkInformation instances.
// .SECTION Description
// vtkInformationVector stores a vector of zero or more vtkInformation
// objects corresponding to the input or output information for a
// vtkAlgorithm. An instance of this class is passed to
// vtkAlgorithm::ProcessRequest calls.
