/**
* 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.
