[vtkusers] vtkDICOMImageReader -> vtkCutter -> vtkMarchingCubes

[Jinyoung Hwang]

Hi vtkers,

I uploaded a method to read a .vtk file in
http://www.vtk.org/Wiki/Read_a_.vtk_file.
Besides, I linked "test.vtk" and raw data on my ftp, so you can freely
access to download.
It's my first time to post my code in wiki, some mistakes might be happened.
:)

Happy new year.

Jinyoung
