 *
 * `state` is an object that will contain the full application state.
 * These can be accessed via the name of the service along with the associating state property.
 * For example, `state.[ServiceName].[ServiceStateProperty]`
 *
 * `actions` is an object that will contain the full application launch actions.
 * These can be accessed via the name of the service along with the associating action.
 * For example, `actions.[ServiceName].[LaunchAction]`
