Vocabulary Import Tips

Run into this error:

ImportError: No module named schema.vocabulary

Fix it by changing the imports in vocabulary.py, from:

from zope.interface import implements
from zope.app.schema.vocabulary import IVocabularyFactory
from zope.schema.vocabulary import SimpleVocabulary

to:

from zope.interface import implements
from zope.schema.interfaces import IVocabularyFactory
from zope.schema.vocabulary import SimpleVocabulary

zope.app.schema 3.5.0 removes deprecated vocabulary directive.
