/**
* Purpose: Font sizer class, handles increasing and decreasing font size
of a page.
* It increases the font in 10% increments. By getting the level / 10 + 1.
i.e. level 2 is .2 + 1 so 1.2 or 120%.
*
* Requires: JQuery and the JQuery cookies plugin.
*
* Use: Setup the fontsizer $.FontSizer.Init(options); the two options are
min and max, for the min level and max level.
* Defaults are min: -3 and max: 5.
*
* Author: Stefan Sedich ([EMAIL PROTECTED]
* Edited: Dion Foster 2009-04-17 to include quick print functionality and
* also onclick event bindings. Extended the options to also include
* the "divid" of the div you want to increase/decrease/print.
