/*
1. This code allows the text to be resized based on the classes. The classes used should be case-sensitive.
(should be exactly the same as defined in the css stylesheets). 
2. A list of classes used should be specified in the Array styles
3. The original sizes of the fonts should be provided as shown in pixels.
4. The maximum number (in pixels) should be provided for each of the css styles in the array max,
 so that the maximum text size does not exceed this size.
5. The minimum number (in pixels) should be provided for each of the css styles in the array min,
 so that the minimum text size does not go below this size.
6. This script uses cookies to store the current font-size.
7. NOTE: This functionality over rides the browser text resize functionality.
