filesPath(/* options */) {
    return path.join(this.path, 'files');
  }
Hook to specify the path to the blueprint's files. By default this is
    `path.join(this.path, 'files)`.

    This can be used to customize which set of files to install based on options
    or environmental variables. It defaults to the `files` directory within the
    blueprint's folder.
