 * Usage: (For more details visit 
 * This function can be called inside a $(document).ready()
 * Eg: fontSize("#controls", "#content", 9, 12, 20); where,
 * #controls - where control is the element id, where the controllers will be created.
 * #content - for which element the font size changes to apply. In this case font size of content div will be changed
 * 9 - minimum font size
 * 12 - default font size
 * 20 - maximum font size
