/**
 * File manager form field.
 *
 * Simple filemanager field manager to allow
 * forms to be filled using TableNodes. It only
 * adds files and checks the field contents in the
 * root directory. If you want to run complex actions
 * that involves subdirectories or other repositories
 * than 'Upload a file' you should use steps related with
 * behat_filepicker::i_add_file_from_repository_to_filemanager
 * this is intended to be used with multi-field
 *
 * This field manager allows you to:
 * - Get: A comma-separated list of the root directory
 *   file names, including folders.
 * - Set: Add a file, in case you want to add more than
 *     one file you can always set two table rows using
 *     the same locator.
 * - Match: A comma-separated list of file names.
