/**
 * 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.
