/**
* This function will get a file list using a pattern. You can compare this function with the dir command from
* DOS or the ls command from Unix. The pattern syntax is the same as well.
*
* @remarks
* This will not work recursively on the subdirectories.
*
* @param $pattern (optional) Pattern to which the files should match. If you want multiple items, you can also
* pass them as an array. If the pattern is prefixed with an exclamation mark, the files that
* match this pattern will not be included in the result.
* @param $class (optional) If you specify a not null value for this option, this function will return the
* items in the directory as the indicated class. If an empty string is given, it will return
* the list of filenames instead of objects.
* @param $classes (optional) An array with the classes to include. Standard, it includes YDFSImage, YDFSFile
* and YDFSDirectory classes. If you only need a single class, you can also specify it as a
* string.
* @param $sort_by_date (optional) Sorts the items by date. Default is false.
* @param $sort_order (optional) Whether the sort direction is ascending or descending. Default is "ASC".
*
* @returns Array of YDFile objects for the files that match the pattern.
