pickle support for CGAL objects

[GoogleCodeExporter]

It seems that it is not yet possible to use pickle with objects from CGAL.

I tried : 

from CGAL.CGAL_Polyhedron_3 import Polyhedron_3
import pickle
polyhedron=Polyhedron_3()
filename='datafile'
with open( filename,'w') as f: 
    pickle.dump(polyhedron,f)

And I get the error "TypeError: can't pickle SwigPyObject objects"
on the line
File "C:\Python27\Lib\copy_reg.py", line 70, in _reduce_ex
  raise TypeError, "can't pickle %s objects" % base.__name__

Maybe this could be done by defining __getstate__ and __setstate_ methods in 
the c++ code ?

Are there plans to add pickle support to the cgal-bindings?
