/**
 * Connects RouterModule with StoreModule.
 *
 * During the navigation, before any guards or resolvers run, the router will dispatch
 * a ROUTER_NAVIGATION action, which has the following signature:
 *
 * ```
 * export type RouterNavigationPayload = {
 *   routerState: SerializedRouterStateSnapshot,
 *   event: RoutesRecognized
 * }
 * ```
 *
 * Either a reducer or an effect can be invoked in response to this action.
 * If the invoked reducer throws, the navigation will be canceled.
 *
 * If navigation gets canceled because of a guard, a ROUTER_CANCEL action will be
 * dispatched. If navigation results in an error, a ROUTER_ERROR action will be dispatched.
 *
 * Both ROUTER_CANCEL and ROUTER_ERROR contain the store state before the navigation
 * which can be used to restore the consistency of the store.
 *
 * Usage:
 *
 * ```typescript
 * @NgModule({
 *   declarations: [AppCmp, SimpleCmp],
 *   imports: [
 *     BrowserModule,
 *     StoreModule.forRoot(mapOfReducers),
 *     RouterModule.forRoot([
