[Zope-Checkins] CVS: Zope3/lib/python/Zope/App/OFS/PropertySets - IPropertySet.py:1.1.2.1 IPropertySetDef.py:1.1.2.1 PropertySetDef.py:1.1.2.1 __init__.py:1.1.2.1

[R. David Murray]

Update of /cvs-repository/Zope3/lib/python/Zope/App/OFS/PropertySets
In directory cvs.zope.org:/tmp/cvs-serv985/PropertySets

Added Files:
      Tag: Zope-3x-branch
	IPropertySet.py IPropertySetDef.py PropertySetDef.py 
	__init__.py 
Log Message:
Initial checkin of PropertySet work done at the NY sprint by
R. David Murray and Nikheel Dhekne.  PropertySetDef is more
or less working, and the Interface for PropertySet is defined.
This code is actually a little behind the recent changes
to the use case/example.
