		 * The Effect.Corner class provides a simple way of styling DOM elements.  
		 *
		 * Effect.Corner constructor takes two arguments:  new Effect.Corner(element, "effect corners width")
		 *
		 *   effect:  The name of the effect to apply, such as round or bevel. 
		 *            If you don't specify an effect, rounding is used.
		 *
		 *   corners: The corners can be one or more of top, bottom, tr, tl, br, or bl. 
		 *            By default, all four corners are adorned. 
		 *
		 *   width:   The width specifies the width of the effect; in the case of rounded corners this 
		 *            will be the radius of the width. 
		 *            Specify this value using the px suffix such as 10px, and yes it must be pixels.
		 *
		 * For more details see: http://methvin.com/jquery/jq-corner.html
		 * For a full demo see:  http://malsup.com/jquery/corner/
		 *
		 *
		 * @example new Effect.Corner(element);
		 * @desc Create round, 10px corners
