Example 8: Order information (menu item 3 continued)

In the previous examples you created an application which received an incoming call and presented a menu to the caller. You wrote functionality for the third menu item that allowed the caller to order an item from a catalog. In this example you will create another class which will represent information extracted from a database, in a form that can be played to the caller. This example introduces the Playable interface, and the AudioCurrency and AudioDate media objects.
