/* fontSize() is a method of dynamically changing the size of text on a page. Instead of changing the text size directly, it adds/changes a class to the body tag.
The class ends in an integer, which is incremented or decremented, depending on whether you pass "larger" or "smaller" to the function. You can set a maximum and a minimum for the integer (can be positive or negative). The default integer is 0.
	"fontSize0" = natural font size (equivalent to no class in body tag)
	"fontSize1" = font size +1 larger
	"fontSize-1" = font size -1 smaller
The actual change in font size is accomplished through CSS. You'll need to add selectors to your style sheet for the range of possible classes (as determined by your min and max values). This means you can change other things besides font size (line height, spacing, etc.) or do fun things like gray-out the controls when you reach a maximum or minimum.
fontSize also sets a cookie with your preference and fontSizeInit reads it on page load. */
