// * This javascript function when called will create two cookies: SARECENTVIEW  and SARECENTVIEW_COUNTER
// *   1.  SARECENTVIEW cookie will store the most 3 recent viewed product.  There will be no duplication of the product.
// *                    The cookie will have this format:  pid_<i>~~~<productId>@pname_<i>~~~<productName>@purl_<i>~~~<productURL>@
// *				    where <i> can be 1,2, or 3
// *   2.  SARECENTVIEW_COUNTER cookie will store the current <i> value.  This will help us know the number of the products have been stored in the SARECENTVIEW cookie so far
