// .NAME vtkMultiGroupDataInformation - hierarchical information collection
// .SECTION Description
// vtkMultiGroupDataInformation stores information objects in a structure
// corresponding to that of a multi-group dataset. This is essentially a
// vector of vectors of information object pointers. Each entry in the
// outer vector corresponds to one group, whereas each entry in the inner
// vector corresponds to one dataset.
