Hello

I am trying to write a triangulation to a file and to read it from there 
again. I thought this can be done simply like this:
        outfile << triangulation_;
and later
        infile >> triangulation_;

Writing works fine, but using the read operator gives a compiler error:

1>C:\Program Files\CGAL-4.6.2\include\CGAL/Triangulation.h(1270): error

It seems there is no "Triangulation::new_vertex()" but only a 
"Triangulation::new_vertex(const Point & p)". Shouldn't there be a version of 
this method without an argument, as the point will be read in a later step?

Thanks,
Daniel
