2 * stickyfloat - jQuery plugin for verticaly floating anything in a constrained area
3 * 
4 * Example: jQuery('#menu').stickyfloat({duration: 400});
5 * parameters:
6 * 		duration 	(200)	 - the duration of the animation
7 *		startOffset (number) - the amount of scroll offset after the animations kicks in
8 *		offsetY		(number) - the offset from the top when the object is animated
9 *		lockBottom	(true)	 - set to false if you don't want your floating box to stop at parent's bottom
10 *		delay		(0)		 - delay in milliseconds  until the animnations starts
11		easing		(linear) - easing function (jQuery has by default only 'swing' & 'linear')
12 * $Version: 08.10.2011 r2
13 * $Version: 05.16.2009 r1
