Implement a function to fetch comments at line end and use it to preserve
comments. Change the regular expressions used to parse lines to be more aware
of whitespaces between terms. Add automatic value and comment indentation
to produce cleaner output.
Add an ini writer that respects the file structure and the comments that may be
already present in the config file. Move Application/Config.php into
Config/Config.php.
