/**
 * Class FilesDataHandler
 *
 * Helper for dealing with PHP's $_FILES. Instead of working with a sometimes puzzling array, with file info
 * dispersed throughout, creates a single collection of FileSubmissionInterface objects. This collection is a
 * one-dimensional list, where identifiers are the HTML input names.
 * Eg, access all file info for a file input named "file1" using
 *
 * ```
 * $data_handler = LoaderFactory::getLoader()->load(' EventEspresso\core\services\request\files\FilesDataHandler');
 * $file = $data_handler->getFileObject('file1);
 * ```
 *
 * and for a file input named "my[great][file][input]", use the same code but change the last line to:
 *
 * ```
 * $file = $data_handler->getFileObject('my[great][file][input]');
 * ```
 *
 * In both cases, $file will be a FileSubmissionInterface object, containing the file's name, temporary filepath, size,
 * error code, and helpers to get its mime type and extension.
