/**
 * The corner() method provides a simple way of styling DOM elements.  
 *
 * corner() takes a single string argument:  $().corner("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.

 * @example $('.adorn').corner();
 * @desc Create round, 10px corners 
 *
 * @example $('.adorn').corner("25px");
 * @desc Create round, 25px corners 
 *
 * @example $('.adorn').corner("notch bottom");
 * @desc Create notched, 10px corners on bottom only
 *
 * @example $('.adorn').corner("tr dog 25px");
 * @desc Create dogeared, 25px corner on the top-right corner only
 *
 * @example $('.adorn').corner("round 8px").parent().css('padding', '4px').corner("round 10px");
 * @desc Create a rounded border effect by styling both the element and its parent
