// .NAME vtkStructuredData - abstract class for topologically regular data
// .SECTION Description
// vtkStructuredData is an abstract class that specifies an interface for
// topologically regular data. Regular data is data that can be accessed
// in rectangular fashion using an i-j-k index. A finite difference grid,
// a volume, or a pixmap are all considered regular.
