[vtkusers] Java Example for ProbeComb

[Todd Simons]

 Hello all,

I'm a relatively new VTK developer.  I am using Java as the gui for my VTK
applications.  I had a hard time getting started and finding examples
written in Java.  I have ported a dozen examples to Java to get familiar
with it.  I wanted to post my examples so other Java enthusiasts could get
up to speed on VTK a bit more easily.  I hope this helps.

Best Regards,
Todd

    This shows how to probe a dataset with a plane.
    The probed data is then contoured.
