/**
* 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.
