- remove subdirectories of include/CGAL/Surface_mesher: files of Criteria/
and Oracles/ are moved one step back.
- repear the polyhedral oracle
- Implicit_oracle.h is now Implicit_surface_oracle.h (and the class has
been renamed too.
- no longer "Kernel_point" trick in Implicit_surface_oracle.h
- *but* "Kernel_point" trick is needed in Polyhedral_oracle.h! :-(
** In Mesh_3:
- repear examples/Mesh_3/polyhedral_surface_mesher.C
- add two input files in ./inputs/*.off (with their medit files)
