/* stickyfloat - jQuery plugin for verticaly floating anything in a constrained area
* 
* Example: jQuery('#menu').stickyfloat({duration: 400});
* parameters:
*         duration     - the duration of the animation
*        startOffset - the amount of scroll offset after it the animations kicks in
*        offsetY        - the offset from the top when the object is animated
*        lockBottom    - 'true' by default, set to false if you don't want your floating box to stop at parent's bottom
