 * cssjs
 * written by Christian Heilmann (http://icant.co.uk)
 * eases the dynamic application of CSS classes via DOM
 * parameters: action a, object o and class names c1 and c2 (c2 optional)
 * actions: swap exchanges c1 and c2 in object o
 *			add adds class c1 to 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'),'bar','baz');
