  Automatically adjust the font size within a fluid width/height div

  Options:
   * prefHeight - The max height of div container, must be in px. use the max-height percentage from your CSS, then use firebug to determine actual px at the max height.  ie: 200, defaults to 500
   * aDrop: additional font decrease from new size.  Defaults to 1, make zero for none.  ie: .5 or 0 or 2.  Normally, this would be the default of 1.
