* you should be aware that this class shares the same behavior, especially with
* regards to boolean and null values.
*
* In addition to the native parse_ini_file features, IniReader also allows you
* to create nested array structures through usage of . delimited names. This allows
* you to create nested arrays structures in an ini config file. For example:
*
* `db.password = secret` would turn into `array('db' => array('password' => 'secret'))`
*
* You can nest properties as deeply as needed using .'s. IniReader also manipulates
* how the special ini values of 'yes', 'no', 'on', 'off', 'null' are handled.
* These values will be converted to their boolean equivalents.
