Log Message:
Draft implementation of 'addClassAdvisor()' API, per discussions with
Steve Alexander.  This is a proposed API for "class advisors" such as Zope
3's proposed new interface declaration API.  'addClassAdvisor()' installs
code in a containing class statement that will invoke a callback to wrap
the containing class upon its creation.  I'll be adding support code to
the module inheritance system so that module inheritance won't break in
the presence of such "magic" advisor functions, as long as they use a
compatible implementation of 'addClassAdvisor()'.
