In directory cvs.zope.org:/tmp/cvs-serv26714/App/OFS/Container

Modified Files:
      Tag: Zope-3x-branch
	SampleContainer.py 
Added Files:
      Tag: Zope-3x-branch
	BTreeContainer.py 
Log Message:
Oops. The class (formerly known as Container) in
Zope.App.OFS.Container.SampleContainer isn't really useful for
production use directly, because it doesn;t follow the rules of
persistence. 

Added a BTreeContainer that is suitable.

Changes ServiceManager to use it.

This module provides a sample container implementation.

This is primarily for testing purposes.

It might be useful as a mix-in for some classes, but many classes will
need a very different implementation.
