//	  Function to create or update a cookie.
//	  name - String object containing the cookie name.
//	  value	  - String object containing the cookie value.	May contain
//				  any valid string characters.
//	  [expires]   - Date object containing the expiration data of the cookie.  If
//				  omitted or null, expires the cookie at the end of the current session.
//	  [path]	  - String object indicating the path for which the cookie is valid.
//				  If omitted or null, uses the path of the calling document.
//	  [domain]	  - String object indicating the domain for which the cookie is
//				  valid.	If omitted or null, uses the domain of the calling document.
//	  [secure]	  - Boolean (true/false) value indicating whether cookie transmission
//				requires a secure channel (HTTPS).	
//	The first two parameters are required.	The others, if supplied, must
//	be passed in the order listed above.  To omit an unused optional field,
//	use null as a place holder.  For example, to call setCookie using name,
//	value and path, you would code:
//
//		setCookie ("myCookieName", "myCookieValue", null, "/");
//
//	Note that trailing omitted parameters do not require a placeholder.
//
//	To set a secure cookie for path "/myPath", that expires after the
//	current session, you might code:
//
//		setCookie (myCookieVar, cookieValueVar, null, "/myPath", null, true);
