/**
* 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).
