new storage model tutorial on the wiki

The JazzTalk walkthrough showed how to craft a very simple storage model
containing one class with a single attribute. JazzTalk is a good
introduction to storage model development but it will likely leave Jazz

models. The JazzBot walkthrough is intended to answer such questions.
This walkthrough is named JazzBot for two reasons. First because it is a
"Bag of Tricks" (BOT) showing a variety of aspects of storage model
design that go beyond JazzTalk, and second because it uses robots as a
metaphor to drive the example.
