+ * This method is the main entry point to an angular application.

+ *
+ *   1. Locating the root element of the application,
+ *   2. Creating Angular [NgZone]
+ *   3. Inside the [NgZone] create an injector
+ *   4. Retrieve the [Compiler] and compile the root eleement
+ *
+ *
+ * # Parameters:
+ *
+ *   - [module] Option application module to add to the [Injector].
+ *   - [modules] Optional list of [Module]s to add to the [Injector] (if more than one is needed).
+ *   - [element] Optional root element of the application. If non specified, the
+ *     the root element is looked up using the [selector]. If selector can not
+ *     identify a root, the root [HTML] element is used for bootstraping.
+ *   - [selector] Optional CSS selector used to locate the root element for the application.
+ *   - [injectorFactor] Optional factory responsible for creating the injector.
+ *
+ *
+ *
+ * # A typical way to boostrap an Angular application:
+ *
+ *     Module myAppModule = new Module();
+ *     myAppModule.type(MyType);
+ *     ....
+ *     Injector injector = ngBootstrap(module: myAppModule);
