//The purpose of this script is to correct the format of the URLs used within the anchor tags surrounding the "Directions to Investor Center" links on the 
//HTML pages that are output by the script at the following location: /dfs/personal/src/gen/centers/centers.pl
//These changes were required in order to support the new Branch Locator application launched in March of 2012.
//This script requires jquery-1.7.1.min.js
