 *			'contentElements': 	'#id .classname', 	//[required] CSS selector to select all content elements
 *			'buttons': 			['#id .classname a'],//[required] Array with CSS selectors to select all the buttons that activate a screen, uses the element his name parameter as an id to display a screen element
 *			'activeClass': 		'active', 			//[optional] Default is 'active' this is the name of the class that will be added to a tab that is active and linked to the content that is shown
 *			'autoswitch': 		true, 				//[optional] Default is false, makes him loop automatic through tabs
 *			'rolloverDelay': 	500, 				//[optional] Default is 0, miliseconds before he activates the tab
 *			'autoDelay': 		3000 				//[optional] Default is 100 (0 could make a slow pc go nuts), miliseconds before he activates the next tab if autoswitch is set true
 *			'display':			'block'				//[optional] Default block, can give another display type to switch through when hiding and showing content
