// .NAME vtkDataObjectGenerator - produces simple (composite or atomic) data
// sets for testing.
// .SECTION Description
// vtkDataObjectGenerator parses a string and produces dataobjects from the
// dataobject template names it sees in the string. For example, if the string
// contains "ID1" the generator will create a vtkImageData. "UF1", "RG1",
// "SG1", "PD1", and "UG1" will produce vtkUniformGrid, vtkRectilinearGrid,
// vtkStructuredGrid, vtkPolyData and vtkUnstructuredGrid respectively.
// "PD2" will produce an alternate vtkPolyData. You
// can compose composite datasets from the atomic ones listed above
// by placing them within one of the two composite dataset identifiers
// - "MB{}" or "HB[]". "MB{ ID1 PD1 MB{} }" for example will create a
// vtkMultiBlockDataSet consisting of three blocks: image data, poly data,
// multi-block (empty). Hierarchical Box data sets additionally require
// the notion of groups, declared within "()" braces, to specify AMR depth.
// "HB[ (UF1)(UF1)(UF1) ]" will create a vtkHierarchicalBoxDataSet representing
// an octree that is three levels deep, in which the firstmost cell in each level
// is refined.
