2121   * A state is a step in a workflow that when set will trigger the controllers
2122   * for the regions to be updated as specified in the frame.
2123   *
2124   * A state has an event-driven lifecycle:
2125   *
2126   *     'ready'      triggers when a state is added to a state machine's collection.
2127   *     'activate'   triggers when a state is activated by a state machine.
2128   *     'deactivate' triggers when a state is deactivated by a state machine.
2129   *     'reset'      is not triggered automatically. It should be invoked by the
2130   *                  proper controller to reset the state to its default.
