/*
INSTRUCTIONS FOR QUERY STRING FUNCTIONS

1. It's recommended that you place this script in a separate
   file named "queryString.js". Then link to it with
   a the below code.
   <script language="javascript" type="text/javascript" src="queryString.js">
   </script>

2. Next, start a separate <script></script> block that will
   call the actual queryString functions.

3. Prototypes of the queryString functions.
      stripQuery([URLString|LocationObject]) //returns value of the search
                                       //part of the location
      queryString(key, [URLString|LocationObject])
      formatQuery(keyArray,valueArray,[URLString])
