00017 * DESCRIPTION:
00018 *
00019 * User Interface Object base class. All user interface modules are derived
00020 * from this; it provides methods for registering with the command processor
00021 * and 'signing up' for which commands it is interested in, as well as
00022 * generating commands and events.
