PyCont not being pickable

[mdepitta]

When attempting to save PyCont (ContClass) objects, method saveObject gives error:

Example:
(import PyDSTool as dst)
DSargs - ode system;
ode - generator
traj - trajectory
pts - some points
PC - ContClass object

$ dst.saveObjects([DSargs,ode,traj,pts,PC],'chain3.sav',force=True)

Error:

TypeError Traceback (most recent call last)
dst.saveObjects([DSargs,ode,traj,pts,PC],'chain3.sav',force=True)
/home/maurizio/Downloads/PyDSTool/utils.pyc in saveObjects(objlist, filename, force)
628 for obj in objlist:
629 try:
--> 630 pickle.dump(obj, pklfile, opt)
631 except:
632 if hasattr(obj, 'name'):

TypeError: expected string or Unicode object, NoneType found

Failed to save object 'ContClass of model chain3'

---

If I leave out the PC object from my list instead, everything seem to work fine.

dill may now be able to serialize PyCont, according to this
