i.e. var  mycookie = new cookieClass('test',10)

				counter starts in 10
				visible in each page in the website

i.e. var  mycookie = new cookieClass('test',,'/catalog')   
				cookie name = 'test'
				last only for the session 
				counter starts in zero
				if this cookie is created by http://airage.com/catalog/widgets/index.asp
				then the visibity of the cookie is FROM http://airage.com/catalog/ and any sublevel

i.e. var  mycookie = new cookieClass('test',5,,32)

				last for 32 days
				counter starts in 5
				visible in each page in the website
