	Bounce
	Created in February 2008 by Ryan O'Dell
	Version 1.0
	
	Requires
	jquery.js
	jquery-easing.js
	
	CSS for elements that you use along with the class (bounceclass) that is being used to wrap the elements (default: mybounce)
	
	Use this script to make elements of your page include an open/close bar, along with an elasticated bounce effect
	
	Examples
	$('textarea').bounce();	// this would turn all 'textarea' elements on the page in to bouncy text areas
	
	// with config options
	$('textarea').bounce({bottom: false});	// as above, but positioning the bar at the top
	$('textarea').bounce({bottom: false, open: true});	// as above, but all are open to begin with
	$('textarea').bounce({bottom: false, open: true}).openBouncer(2);	// as above, but open number 2 bouncer

	// all config options: min  (size), max  (size), bottom  (boolean), string  (text to click), open  (boolean), bounceclass  (string)
	
	$('textarea').bounceOpen(2);	// opens an individual bouncer (rather than using the config: open )
	$('textarea').bounceOpen(1,2,5);	// opens a number of individual bouncer's (rather than using the config: open )
