localize() public static method
Returns the localized version of a specified file. The searching is based on the specified language code. In particular, a file with the same name will be looked for under the subdirectory whose name is the same as the language code. For example, given the file "path/to/view.php" and language code "zh-CN", the localized file will be looked for as "path/to/zh-CN/view.php". If the file is not found, it will try a fallback with just a language code that is "zh"
