by default when you create an accordion, you have all those classes applied to the header

in some accordions on my site I do not want rounded corners, and I would love to disable them by simply doing something like

$( ".selector" )
   .accordion({ styles: { 'header': 'ui-accordion-header ui-state-default ui-state-active'} });

So that if I do not apply some default classes I simply override the default on the accordion() call instead of overriding the styles in css
