Creates and initializes a new Angular application that is the default project for a new workspace.

Provides interactive prompts for optional configuration, such as adding routing support.
All prompts can safely be allowed to default.

* The new workspace folder is given the specified project name, and contains configuration files at the top level.

* By default, the files for a new initial application (with the same name as the workspace) are placed in the `src/` subfolder. Corresponding end-to-end tests are placed in the `e2e/` subfolder.

* The new application's configuration appears in the `projects` section of the `angular.json` workspace configuration file, under its project name.

* Subsequent applications that you generate in the workspace reside in the `projects/` subfolder.

If you plan to have multiple applications in the workspace, you can create an empty workspace by setting the `--createApplication` option to false.
You can then use `ng generate application` to create an initial application.
This allows a workspace name different from the initial app name, and ensures that all applications reside in the `/projects` subfolder, matching the structure of the configuration file.
