[Martijn Faassen]

Update of /cvs-repository/Zope3/lib/python/Zope/App/schemagen/tests
In directory cvs.zope.org:/tmp/cvs-serv11175/tests

Added Files:
	test_modulegen.py 
Log Message:
Added code that can generate module source from field information
automatically. The generated source contains an interface based on the 
provided fields, as well as a class implementing that schema using
FieldProperty.
