/*
Differences from offical CC:
	- Boxes are not fixed size and will auto size to content
	- Backgrounds aligned to bottom won't work correctly so align to top if you need to tile

Usage:
	Will now autoMagically apply borders via the CSS declarations
	Safari, Mozilla, and Chrome all support rounded borders via
	
	-webkit-border-radius, and -moz-border-radius
		
	So to make curvycorners work with any major browser simply add the following
	CSS declarations and it should be good to go...
	
	.round { 
		-webkit-border-radius: 25px;
	    -moz-border-radius: 25px;
	    CCborderRadius: 25px;
	}
	
You can still use the direct syntax:

	$('.myBox').corner();
	
Add the styles in the page itself to support Opera!
