// .NAME vtkMCubesReader - read binary marching cubes file
// .SECTION Description
// vtkMCubesReader is a source object that reads binary marching cubes
// files. (Marching cubes is an isosurfacing technique that generates 
// many triangles). The binary format is supported by B. Lorensen's
// marching cubes program (and the vtkSliceCubes object). The format 
// repeats point coordinates, so this object will merge the points 
// with a vtkLocator object. You can choose to supply the vtkLocator 
// or use the default.
// .SECTION Caveats
// Binary files assumed written in sun/hp/sgi form.
//
// Because points are merged when read, degenerate triangles may be removed.
// Thus the number of triangles read may be fewer than the number of triangles
// written.
// .SECTION See Also
// vtkMarchingCubes vtkSliceCubes
