[Catalyst] Program the logic

[Zbigniew Lukasiak]

I dont' agree with the statement that all the application logic should go
into the Controller.  In my opinion in the Controller you should have only
the code that is directly web related - all the rest should go into the
Model.  This way you can call your business logic from a cron script without
the overhead of all the web stuff.
