Creates and initializes a new Angular app 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 app (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 app's configuration appears in the projects section of the angular.json workspace configuration file, under its project name.
• Subsequent apps that you generate in the workspace reside in the projects/ subfolder.

If you plan to have multiple apps 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 app. This allows a workspace name different from the initial app name, and ensures that all apps reside in the /projects subfolder, matching the structure of the configuration file.
