Changes to the long description, putting a more relevant

bibliographic reference.
Changed the order for maintainers, since I would like to 
have a firsthand look at what is happening in this package.

+This package will not be documented for CGAL-3.4. It is a stripped down version
+of a generic tool (generic in terms of inputs and queries), which is still under 
+development. It is already added to the trunk because it is used in the Polyhedron 
+Demo to remesh polyhedra. 
+
+For CGAL-3.5, we hope to integrate the fully generic version, with parallelism.
