Interface RootModule

If a UI-Router Module needs to perform some configuration (such as registering parameter types or Transition Hooks) a configClass should be supplied.

Mark the class as @Injectable() and inject any required dependencies. When the module is being loaded, an instance will be created and injected.

Example: ```js

injectable

() export class MyUIRouterConfig { // The constructor may be injected constructor(uiRouter: UIRouter) { const requireAuthentication = (transition: Transition) => { let injector = transition.injector(); if (!injector.get(AuthService).isAuthenticated()) { return uiRouter.stateService.target('login'); } }

uiRouter.transitionService.onBefore({ to: (state) => state.requiresAuth }, requireAuthentication);

let builtInStringType = urlMatcherFactory.type('string');
let slugType = Object.assign({}, builtInStringType, { encode: (str) => str, decode: (str) => str });
uiRouter.urlMatcherFactory.type('slug', slugType);

} } ```

```js

ngmodule

({ imports: [ UIRouterModule.forChild({ states: STATES, configClass: MyUIRouterConfig }); ] }) class MyModule {} ```

This list of Ng2StateDeclaration objects will be registered with the StateRegistry. Also, the components that the states route to will be added to entryComponents so they will be compiled.
