Class: Scroller
    Adds a scrollbar to a specific div. The scrollbar is implemented using a Script.aculo.us slider.
    The class reparents the original div, creates a slider and ties the reparented div to the slider,
    setting any properties necessary on the divs to make it all work. The scrollbar can be styled using
    CSS. The track of the scrollbar has class 'scroll-track', 'scroll-track-top' and 'scroll-track-bot',
    the thumb has class 'scroll-handle', 'scroll-handle-top' and 'scroll-handle-bot'.
    
properties:
    myIndex - an integer used to generate a unique ID for use in, for example, div ids.
    outerBox - the div that holds the scrollpane + scrollbar
    innerBox - the div that holds the scrollpane
    innerHeight - the height of the inner box.
    viewportHeight - the height of the view onto the scrolled div.
    track - a div that holds the script.aculo.us slider (the scrollbar)
    trackHeight - the height of the slider
    handle - the div for the 'thumb' of the scrollbar
    handleHeight - the height of the thumb
    slider - the script.aculo.us slider itself
    ieDecreaseBy - a fudge factor used when calculating the width of innerBox
