	// summary:
	//		A Media Player UI widget for all types of dojox.av and AIR media.
	//
	// description:
	//		Currently for markup only. All controls should reside as child
	//		nodes within the Player node. 'controlType' is used to determine
	//		the placement of the control. If no type or an unrecoginized type 
	//		is used, it will be left-aligned in the same row as the volume.
	//	Note:
	//		Be sure to use 'controlType' as a node attribute. It is not a
	//		property of the widget.
	//
	// example:
	//		|	<div dojoType="dojox.av.widget.Player" playerWidth="100%">
    //		| 		<div controlType="video" initialVolume=".1"
	//		| 			mediaUrl="video/Grog.flv" autoPlay="true" 
	//		|			isDebug="false" dojoType="dojox.av.FLVideo"></div>
    //		|     	<div controlType="play" dojoType="dojox.av.widget.PlayButton"></div>
    //		|     	<div controlType="volume" dojoType="dojox.av.widget.VolumeButton"></div>
    //		|     	<div controlType="progress" dojoType="dojox.av.widget.ProgressSlider"></div>
    //		|     	<div controlType="status" dojoType="dojox.av.widget.Status"></div>
    //		| </div>
	//
	// playerWidth: /* Number or String */
	//		Sets the width of the player (not the video size)
	//		Number will be converted to pixels
	//		String will be used literally. EX: "320px" or "100%"
	playerWidth: "480px",
