[Zope-CMF] Proposal: MemberDataFactory

Sure.  Example use cases are fairly simple things like:

  - I set members to have first_name, last_name, job_title attributes 
and
    I want to give them an attribute "proper_name" that returns
     '%s %s (%s)' % (first_name, last_name, job_title);

  - I want to provide a standardised sortable name for ordering rows,
     e.g. (last_name + ' ' + first_name).lower()

  - I want to adjust the setProperties method to add a 'modified'
    attribute that's adjusted on every change of details

For sites with integration we use PAS.  But for small sites with very 
simple member requirements, the MemberDataTool generally does most of 
what's required out of the box.
