[Zope] - Product API tutorial updated

Hi guys: I've got a new version of the Product API Tutorial on-line at: http://www.zope.org/Documentation/Reference/Tutorial So now you can read it without downloading the whole thing. Of course, you can still download it along with sample files and a completed sample Product at: http://www.zope.org/Documentation/Reference/ProductTutorial.tar.gz The tutorial has been updated a little to clean up language and add some discussion of project requirements and analysis, and now comes with an HTML as well as a text version. I'm still looking for criticism, so send it on in. Have fun, and have a happy new year! -Amos
