     * A helper function that allows an Angular component to be used from AngularJS.
     *
     * *Part of the [upgrade/static](api?query=upgrade%2Fstatic)
     * library for hybrid upgrade apps that support AOT compilation*
     *
     * This helper function returns a factory function to be used for registering
     * an AngularJS wrapper directive for "downgrading" an Angular component.
     *
     * @usageNotes
     * ### Examples
     *
     * Let's assume that you have an Angular component called `ng2Heroes` that needs
     * to be made available in AngularJS templates.
     *
     * {@example upgrade/static/ts/full/module.ts region="ng2-heroes"}
     *
     * We must create an AngularJS [directive](https://docs.angularjs.org/guide/directive)
     * that will make this Angular component available inside AngularJS templates.
     * The `downgradeComponent()` function returns a factory function that we
     * can use to define the AngularJS directive that wraps the "downgraded" component.
     *
     * {@example upgrade/static/ts/full/module.ts region="ng2-heroes-wrapper"}
     *
     * For more details and examples on downgrading Angular components to AngularJS components please
     * visit the [Upgrade guide](guide/upgrade#using-angular-components-from-angularjs-code).
     *
     * @param info contains information about the Component that is being downgraded:
     *
     * - `component: Type<any>`: The type of the Component that will be downgraded
     * - `downgradedModule?: string`: The name of the downgraded module (if any) that the component
     *   "belongs to", as returned by a call to `downgradeModule()`. It is the module, whose
     *   corresponding Angular module will be bootstrapped, when the component needs to be instantiated.
     *   <br />
     *   (This option is only necessary when using `downgradeModule()` to downgrade more than one
     *   Angular module.)
     * - `propagateDigest?: boolean`: Whether to perform {@link ChangeDetectorRef#detectChanges
     *   change detection} on the component on every
     *   [$digest](https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$digest). If set to `false`,
     *   change detection will still be performed when any of the component's inputs changes.
     *   (Default: true)
     *
     * @returns a factory function that can be used to register the component in an
     * AngularJS module.

                    //   on the same tree as the `NgModule` that declares this downgraded component.
                    // - `finalParentInjector` is used for all other injection purposes.
                    //   (Note that Angular knows to only traverse the component-tree part of that injector,
                    //   when looking for an injectable and then switch to the module injector.)

                    // - If there is a parent component (and thus a `parentInjector`) and we are sure that it
                    //   belongs to the same `NgModule` as this downgraded component (e.g. because there is only
                    //   one downgraded module, we use that `parentInjector` as both `finalModuleInjector` and
                    //   `finalParentInjector`.
                    // - If there is a parent component, but it may belong to a different `NgModule`, then we
                    //   use the `parentInjector` as `finalParentInjector` and this downgraded component's
                    //   declaring `NgModule`'s injector as `finalModuleInjector`.
                    //   Note 1: If the `NgModule` is already bootstrapped, we just get its injector (we don't
                    //           bootstrap again).
                    //   Note 2: It is possible that (while there are multiple downgraded modules) this
                    //           downgraded component and its parent component both belong to the same NgModule.
                    //           In that case, we could have used the `parentInjector` as both

     *   For example, it is _OK_ to use a downgraded service in an upgraded component that is only used
     *   from a downgraded Angular component provided by the same Angular module as the injectable, but
     *   it is _not OK_ to use it in an AngularJS component that may be used independently of Angular or
     *   use it in a downgraded Angular component from a different module.

     * Use `UpgradeAdapter` to allow AngularJS and Angular to coexist in a single application.
     *
     * The `UpgradeAdapter` allows:
     * 1. creation of Angular component from AngularJS component directive
     *    (See [UpgradeAdapter#upgradeNg1Component()])
     * 2. creation of AngularJS directive from Angular component.
     *    (See [UpgradeAdapter#downgradeNg2Component()])
     * 3. Bootstrapping of a hybrid Angular application which contains both of the frameworks
     *    coexisting in a single application.
     *
     * @usageNotes
     * ### Mental Model
     *
     * When reasoning about how a hybrid application works it is useful to have a mental model which
     * describes what is happening and explains what is happening at the lowest level.
     *
     * 1. There are two independent frameworks running in a single application, each framework treats
     *    the other as a black box.
     * 2. Each DOM element on the page is owned exactly by one framework. Whichever framework
     *    instantiated the element is the owner. Each framework only updates/interacts with its own
     *    DOM elements and ignores others.
     * 3. AngularJS directives always execute inside AngularJS framework codebase regardless of
     *    where they are instantiated.
     * 4. Angular components always execute inside Angular framework codebase regardless of
     *    where they are instantiated.
     * 5. An AngularJS component can be upgraded to an Angular component. This creates an
     *    Angular directive, which bootstraps the AngularJS component directive in that location.
     * 6. An Angular component can be downgraded to an AngularJS component directive. This creates
     *    an AngularJS directive, which bootstraps the Angular component in that location.
     * 7. Whenever an adapter component is instantiated the host element is owned by the framework
     *    doing the instantiation. The other framework then instantiates and owns the view for that
     *    component. This implies that component bindings will always follow the semantics of the
     *    instantiation framework. The syntax is always that of Angular syntax.
     * 8. AngularJS is always bootstrapped first and owns the bottom most view.
     * 9. The new application is running in Angular zone, and therefore it no longer needs calls to
     *    `$apply()`.
     *
     * ### Example
     *
     * ```
     * const adapter = new UpgradeAdapter(forwardRef(() => MyNg2Module), myCompilerOptions);
     * const module = angular.module('myExample', []);
     * module.directive('ng2Comp', adapter.downgradeNg2Component(Ng2Component));
     *
     * module.directive('ng1Hello', function() {
     *   return {
     *      scope: { title: '=' },
     *      template: 'ng1[Hello {{title}}!](<span ng-transclude></span>)'
     *   };
     * });
     *
     *
     * @Component({
     *   selector: 'ng2-comp',
     *   inputs: ['name'],
     *   template: 'ng2[<ng1-hello [title]="name">transclude</ng1-hello>](<ng-content></ng-content>)',
     *   directives:
     * })

         * 3. `ng-model` is controlled by AngularJS and communicates with the downgraded Angular component
