// Class StickyScroller
// Purpose: Create a fixed scroller
// Parameters:
//  obj: The object that will be scrolling
//  start: What distance from the top (in px) the effect starts
//  end: What distance from the top (in px) the effect ends
//  interval: What scroll distance triggers the callback
//  range: How many pixels after the
//  margin: Margin from the top of the browser
//  distance: How far the obj will move
