general representation of visualization data
helper class to get VTK data object types as string and instantiate them
vtkDataObject is an general representation of visualization data. It serves to encapsulate instance variables and methods for visualization network execution, as well as representing data consisting of a field (i.e., just an unstructured pile of data). This is to be compared with a vtkDataSet, which is data with geometric and/or topological structure.
vtkDataObjects are used to represent arbitrary repositories of data via the vtkFieldData instance variable. These data must be eventually mapped into a concrete subclass of vtkDataSet before they can actually be displayed.
vtkDataObjectTypes is a helper class that supports conversion between integer types defined in vtkType.h and string names as well as creation of data objects from either integer or string types. This class has to be updated every time a new data type is added to VTK.

The ExtentType will be changed to VTK_3D_EXTENT for data objects with 3D structure such as vtkImageData (and its subclass vtkStructuredPoints), vtkRectilinearGrid, and vtkStructuredGrid.
