	// summary:
	//		A widget that creates a stylable file-input button, with optional multi-file selection,
	//		using only HTML elements. Non-HTML5 browsers have fallback options of Flash or an iframe.
	//
	//	description:
	//		A bare-bones, stylable file-input button, with optional multi-file selection. The list
	//		of files is not displayed, that is for you to handle by connecting to the onChange
	//		event, or use the dojox.form.uploader.FileList.
	//
	//		Uploader without plugins does not have any ability to upload - it is for use in forms
	//		where you handle the upload either by a standard POST or with Ajax using an iFrame. This
	//		class is for convenience of multiple files only. No progress events are available.
	//
	//		If the browser supports a file-input with the "multiple" attribute, that will be used.
	//		If the browser does not support "multiple" (ergo, IE) multiple inputs are used,
	//		one for each selection.
	//
	//
	//	uploadOnSelect: Boolean
	//		If true, uploads imediately after a file has been selected. If false,
	//		waits for upload() to be called.
	uploadOnSelect:false,
	//	tabIndex: Number|String
	//		The tab order in the DOM.
	tabIndex:0,
	//	multiple: Boolean
	//		If true and flash mode, multiple files may be selected from the dialog.
	multiple:false,
	//
	//	label: String
	//		The text used in the button that when clicked, opens a system Browse Dialog.
	label:res.label,
	//
	// url: String
	//		The url targeted for upload. An absolute URL is preferred. Relative URLs are
	//		changed to absolute.
	url:"",
	//
	//	name: String
	//		The name attribute needs to end with square brackets: [] as this is the standard way
	//		of handling an attribute "array". This requires a slightly different technique on the
	//		server.
	name:"uploadedfile",
	//
	//	flashFieldName: String
	//		If set, this will be the name of the field of the flash uploaded files that the server
	//		is expecting. If not set, "Flash" is appended to the "name" property.
	flashFieldName:"",
	//
	//	uploadType: String [readonly]
	//		The type of uploader being used. As an alternative to determining the upload type on the
	//		server based on the fieldName, this property could be sent to the server to help
	//		determine what type of parsing should be used.
	uploadType:"form",
	//
	//	showInput: String [const]
	//		Position to show an input which shows selected filename(s). Possible
	//		values are "before", "after", which specifies where the input should
	//		be placed with reference to the containerNode which contains the
	//		label). By default, this is empty string (no such input will be
	//		shown). Specify showInput="before" to mimic the look&feel of a
	//		native file input element.
