Added examples to Zope. Finally Zope comes with some simple example applications. The current examples include automatic navigation devices, a guestbook, a file library and a shopping cart. The examples make use of new features including ZPT (including macros) and sessions.

I set things up to automatically create an Examples folder in the root if one doesn't already exist. I don't know if this is the right thing to do or not. Maybe folks should have to add examples from the product add list.

If you would like to contribute example applications just let me know. I'm open to contributions.
