You can either give your specialist methods to create objects of each type,
which call the respective Racks' newItem() methods, or give your specialist
a single method that determines based on input parameters which class would
be better suited. The choice depends on the requirements of your problem
In either case, the specialist is also the natural place to put the UI
("add forms") for creating the objects.
