[vtkusers] labelling iso-lines

[Bill Lorensen]

Rashed,

I have written a small, simple example that labels contours. It was
fairly simple.
I will "sell" to you.

In return (the cost), you promise:

1) To spend your time to study the example and learn from it.
2) Not ask any questions regarding the example.
3) Report back to the list if you find the example useful.
    For example, "I found this example to be useful in solving my problem."
    or "This example was not helpful, but thank you for the effort."
4) Fix or enhance the example.

I probably won't be able to post the example until tomorrow. So you
have time to think about whether you want to "pay" for it. If you
agree to the cost, I will post it on the wiki sometime tomorrow.

Bill
