Hi, I am the author of the Surface Mesh Generator package in CGAL. As a 
matter 
of fact, I am co-author of the paper you talk about.

The Surface Mesh Generator uses a concept for classes that specify the 
meshing 
criteria:
http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Surface_mesher_ref/Concept_SurfaceMeshCriteria_3.html

The easiest way to tweak you own sizing function is to modify the class
CGAL::Surface_mesh_default_criteria_3<Tr>. You can tweak the code of the 
class 
CGAL::Surface_mesher::Uniform_size_criterion<Tr> in the header 
<CGAL/Surface_mesher/Standard_criteria.h>.

If you manage to publish an article using that software, and I hope you will, 
do you forget to cite CGAL. See that page for suggestions about how to cite
