a bug of visualizer.d.ts for ng2

[zhongsigang]

In node_modules/@uirouter/visualizer/lib/visualizer.d.ts:

import { UIRouter, UIRouterPlugin } from "@uirouter/core";
should be:
import { UIRouter, UIRouterPlugin } from "@uirouter/angular";

If not, the following code will not be compiled:

import {UIRouter} from "@uirouter/angular";
import {Visualizer} from "@uirouter/visualizer";

/** UIRouter Config  */
export function uiRouterConfigFn(router: UIRouter) {
  router.urlService.rules.otherwise({state: 'hello'});

  router.plugin(Visualizer);
}

And the error message is:
ERROR in .../src/app/config/router.config.ts (11,17): Argument of type 'typeof Visualizer' is not assignable to parameter of type 'PluginFactory<UIRouterPlugin>'. Type 'typeof Visualizer' provides no match for the signature '(router: UIRouter, options?: any): UIRouterPlugin'.
Because the UIRouter comes from different files, although they have the same contents.

dependencies:

  "@angular/animations": "^4.0.0",
  ...
  "@uirouter/angular": "^1.0.0-beta.7",
  "@uirouter/visualizer": "^4.0.2",
