Ho, I thought it could handle a polygon soup like the mesh_3 demo.

My dream is to become CGAL QA tester ...

Specifically here I'm trying to accomplish this:

http://cgal-discuss.949826.n4.nabble.com/Surface-remeshing-using-mesh-generation-td4471479.html

Meaning given a defective mesh - preferably a poly soup - generate a clean
mesh. This is a useful utility, since sometimes I get defective meshes,
which trip my algorithms, and this would remedy that.
So I try to find the weakest points of the c2t3 and c3t3 meshers. Up until
now I used c2t3 mesher for extracting isosurfaces, and it tends to fail
roughly at about 5% of the cases (yes, I'll try to give you a small example
next time it happens). Now that Sebastien has provided me with a c3t3 to
polyhedron converter, I think I should switch and use it instead of the c2t3
mesher. Actually isn't the c2t3 became redundant at this point?
