ok. The user knows that the infinite vertex is part of the triangulation 
since this is documented everywhere, I agree that he can also be told 
that this vertex is numbered 0 in the file (this is even already 
documented a few lines before, about the input stream).
So, I just added the same precision in the text for the output stream.
