/**
 * Service to automatically include PHP files from a given directory,
 * relative to the plugin root.
 * 
 * Usage:
 * 
 * In the plugin class call the "add_service" method to add the service.
 * 
 * Example:
 * ```
 * $this->add_service( 'includes_files', new Includes_Files( $this ) );
 * ```
 * 
 * The service will automatically include all PHP files in the 'inc' directory.
 * 
 * To include files from a different directory, pass the directory name as the second argument.
 * 
 * Example:
 * ```
 * $this->add_service( 'includes_files', new Includes_Files( $this, [ 'includes' ] ) );
 * ```
 * 
 * To include files from multiple directories, pass an array of directory names as the second argument.
 * 
 * Example:
 * ```
 * $this->add_service( 'includes_files', new Includes_Files( $this, [ 'includes', 'admin/includes' ] ) );
 * ```
 * 
 * It is recommended to use the 'inc' directory for all plugin includes.
