CommandActivity Class
Represents a digression in the dialog. A command is matched when the user speaks a phrase recognized by the command's grammar. It is different from a DialogEventActivity in that regard. A DialogEventActivity represents a system-initiated event in the dialog flow, while a CommandActivity represents a user-initiated event and the associated handler for the event. The CommandActivity provides the event-subscription data, and the children of the CommandActivity provide the handler logic for the event. Deriving from the CommandActivity is not supported, as it is used by other command activities.
