/**
 * 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:
 * })
 * class Ng2Component {
 * }
 *
 * @NgModule({
 *   declarations: [Ng2Component, adapter.upgradeNg1Component('ng1Hello')],
 *   imports: [BrowserModule]
 * })
 * class MyNg2Module {}
 *
 *
 * document.body.innerHTML = '<ng2-comp name="World">project</ng2-comp>';
 *
 * adapter.bootstrap(document.body, ['myExample']).ready(function() {
 *   expect(document.body.textContent).toEqual(
 *       "ng2[ng1[Hello World!](transclude)](project)");
 * });
 *
 * ```
 *
 * @deprecated Deprecated since v5. Use `upgrade/static` instead, which also supports
 * [Ahead-of-Time compilation](guide/aot-compiler).

     * @usageNotes
     * ### Mental Model
     *
     * 1. The component is instantiated by being listed in AngularJS template. This means that the
     *    host element is controlled by AngularJS, but the component's view will be controlled by
     *    Angular.
     * 2. Even thought the component is instantiated in AngularJS, it will be using Angular
     *    syntax. This has to be done, this way because we must follow Angular components do not
     *    declare how the attributes should be interpreted.
     * 3. `ng-model` is controlled by AngularJS and communicates with the downgraded Angular component
     *    by way of the `ControlValueAccessor` interface from @angular/forms. Only components that
     *    implement this interface are eligible.
     *
     * ### Supported Features
     *
     * - Bindings:
     *   - Attribute: `<comp name="World">`
