The function make_surface_mesh has a parameter number_of_initial_points with 
a 
default value = 20.

In future implementation of make_surface_mesh, we has reserved the 
possibility 
to split that function into two: one with the parameter 
number_of_initial_points without default value, and one without that 
parameter.

With CGAL-3.3, you can implement only the one with the parameter 
number_of_initial_points, if you want.

That iterator is an "output iterator"¹ of value type  You can use 
std::back_inserter(one_vector) for example.
