  * Exenstion File Uploading Class

+ * 	Installation
+	============
+	Copy MY_Upload.php to your application/libraries directory. If you are using a prefix other than MY_ for your classes and/or alternative file paths, adjust accordingly.
+
+	Usage Load the Upload class as usual, in your controller call the function do_multi_upload(). If you are uploading a single file, it'll default to the regular do_upload() method. In the form, set field names to array (e.g. name="userfile[]")
