/**
 *  corner() takes a single string argument:  $('#myDiv').corner("effect corners width")
 *
 *  effect:  name of the effect to apply, such as round, bevel, notch, bite, etc (default is round). 
 *  corners: one or more of: top, bottom, tr, tl, br, or bl.  (default is all corners)
 *  width:   width of the effect; in the case of rounded corners this is the radius. 
 *           specify this value using the px suffix such as 10px (yes, it must be pixels).
