/**
 * Manages a list of INI files where the settings in each INI file merge with or override the
 * settings in the previous INI file.
 *
 * The IniFileChain class manages two types of INI files: multiple default setting files and one
 * user settings file.
 *
 * The default setting files (for example, global.ini.php & common.ini.php) hold the default setting values.
 * The settings in these files are merged recursively, however, array settings in one file will still
 * overwrite settings in the previous file.
 *
 * Default settings files cannot be modified through the IniFileChain class.
 *
 * The user settings file (for example, config.ini.php) holds the actual setting values. Settings in the
 * user settings files overwrite other settings. So array settings will not merge w/ previous values.
 *
 * HTML characters and dollar signs are stored as encoded HTML entities in INI files. This prevents
 * several `parse_ini_file` issues, including one where parse_ini_file tries to insert a variable
 * into a setting value if a string like `"$varname" is present.
