/**
* Returns the localized version of a specified file.
* The searching is based on the specified language code. For a language code such as 'zh_cn',
* this method will check the existence of the following files in order:
* <li>path/to/zh_cn/fileName
* <li>path/to/zh/fileName
* The first existing file will be returned. If no localized file exists, the original file will be returned
* (even if it does not exist.)
* Note, the language codes used here should be in lower-case and the dashes
* be replaced with underscores (e.g. 'en_us' instead of 'en-US').
*
* The searching is based on the specified language code. In particular,
* a file with the same name will be looked for under the subdirectory
* named as the locale ID. For example, given the file "path/to/view.php"
* and locale ID "zh_cn", the localized file will be looked for as
* "path/to/zh_cn/view.php". If the file is not found, the original file
* will be returned.
*
* For consistency, it is recommended that the locale ID is given
* in lower case and in the format of LanguageID_RegionID (e.g. "en_us").
*
* @param string the original file
* @param string the language that the original file is in. If null, the application {@link language} is used.
* @param string the language that the original file is in. If null, the application {@link sourceLanguage source language} is used.
* @param string the desired language that the file should be localized to. If null, the {@link getLanguage application language} will be used.
* @return string the matching localized file. The original file is returned if no localized version is found.
* @return string the matching localized file. The original file is returned if no localized version is found
* or if source language is the same as the desired language.
