 * written by Christian Heilmann (http://icant.co.uk)
 * eases the dynamic application of CSS classes via DOM

 * actions: swap exchanges c1 and c2 in object o

 *			remove removes class c1 from object o
 *			check tests if class c1 is applied to object o
 * example:	cssjs('swap',document.getElementById('foo'));
