docs: // AssetDir returns the file names below a certain
  // directory embedded in the file by go-bindata.
  // For example if you run go-bindata on data/... and data contains the
  // following hierarchy:
  //     data/
  //       foo.txt
  //       img/
  //         a.png
  //         b.png
  // then AssetDir("data") would return []string{"foo.txt", "img"}
  // AssetDir("data/img") would return []string{"a.png", "b.png"}
  // AssetDir("foo.txt") and AssetDir("notexist") would return an error
  // AssetDir("") will return []string{"data"}.
