Replacement async 'it' for testing AngularJs with Mocha.

es5_ng_it.js

  return function(text, fn) {
    it(text, function(done) {
      var $rootScope = $injector.get('$rootScope')
        , fin

      fn(finished);
      while (!fin) {$rootScope.$digest()}
      $rootScope.$digest();
    })

}

// Set up like this at top of test file:
const $it = ngIt(angular.injector(['ng', 'ModuleA']));

// Then use in place of `it`.
