Merge pull request #27 from vvidal/master

Catching exception in Pipeline::run() and allowing empty mesh file read
add OpenMesh_to_CGAL_Mesh and CGAL_Mesh_to_OpenMesh converters,
see OpenMesh_FilterAdapter.cxx for sample:

1) OpenMesh_to_CGAL_Mesh
2) CGAL triangulation
3) CGAL_Mesh_to_OpenMesh

but still problem during writing process (Ricardo, if you can look at this please...)
OpenMesh_FilterAdapter now Ok (thanks Ricardo)
OpenMesh_Mesh and CGAL_Mesh are now templated by TTraits
