 * Desc :    this script is used to manipulate

 *           from webcoder.com
 *
 * usage :   setCookie(name, value, expires) - to save a cookie
 *           getCookie(name)                 - to retrieve a cookies' value
 *           delCookie(name)                 - to delete a cookie
 *
 * Notes :   some added NVP fn's are (maybe these should go into js_standard)
 *           getNVPName(string, deLimiter)
 *           getNVPValue(string, deLimiter)
