I have object defined as `A = Object()` where I specified class Object(): pass
I proceeded to construct attributes, A.b, A.c, etc. Most are lists, some of whose items are lists. I wrote:

```
  outFile = file('A.obj','wb')
  pickle.dump(A,outFile)
  outFile.close()

```

I got error:

```
PicklingError: Can't pickle <class '__main__.Object'>: it's not found as __main__.Object

```

My goal is to be able to dump (and later load) objects.
