  /**
   * method to return the Localized version of the file whose name is passed as an argument. The
   * localization is done based on localization subdirectories under the docBase.
   *
   * <p>The method performs a resource lookup in a manner similar to the one used for JavaHelp
   * resources.
   *
   * <p>Search for localized versions of the file are looked for:
   *
   * <p><docBase> + "/" + language1 + "_" + country1 + "_" + variant1 + file <docBase> + "/" +
   * language1 + "_" + country1 + file <docBase> + "/" + language1 + file <docBase> + "/" +
   * language2 + "_" + country2 + "_" + variant1 + file <docBase> + "/" + language2 + "_" + country2
   * + file <docBase> + "/" + language2 + file <docBase> + file
   *
   * <p>Where language1, country1, variant1 are associated with the Locale passed as an argument and
   * language2, country2, variant are associated with the fallback Locale passed as argument.
   *
   * @param path the pathname for the resource whose localized version we are seeking
   * @param loc the Locale we are interested in.
   * @param fbLoc the fallback Locale to use if unsuccessful
   * @param locType the type of localization required "file", "docbase"
   * @return a String with the path of the "best localized match" for the file whose path has been
   *     passed as argument.
