[Zope-CVS] CVS: Products/AdaptableStorage - Zope2Mapper.py:1.4

[Shane Hathaway]

Update of /cvs-repository/Products/AdaptableStorage
In directory cvs.zope.org:/tmp/cvs-serv31552

Modified Files:
	Zope2Mapper.py 
Log Message:
Added OptionalAspect, a wrapper that disables an aspect if it can't
serialize the object.  This involved refactoring the IAspectSerializer
and IObjectSerializer interfaces.  Thanks, Christian, for discovering
the need for this.
