   * This autoloading setup is really more complicated than it needs to be for most

   * new developers to be productive with a fresh skeleton. It allows autoloading
   * to be correctly configured, regardless of the installation method and keeps
   * the use of composer completely optional. This setup should work fine for
   * most users, however, feel free to configure autoloading however you'd like.
