Ok, so the _runtime_ will add instance variables?

Have a look at this snippet from Todo's nibwrapper.py:

  class ToDoDocumentBase (NSDocument):
      "Base class for class 'ToDoDocument'"
      calendar = IBOutlet("calendar")
      itemList = IBOutlet("itemList")
      dayLabel = IBOutlet("dayLabel")
      statusList = IBOutlet("statusList")

The outlets are class attributes, and will be shared by all instances. Whether
this is correct or not, it is exactly what NibLoader.py mimics.

Do I understand correctly that these (Python) class attributes are more or less
"declarations" for the (Cocoa) runtime?

Just

PS: should we rename NibLoader.py to something more appropriate, too?
