 // the week number is return, and the year number is returned in year
 // for Instance 2001/12/31 is actually the first week in 2002.
 // There is a more mathematical definition, but I will implement it when
 // we are pass our deadline.
 
 // For Weeks that start on Sunday... (ahh... home rolled)
 // okay, if Jan 1 is on Friday or Saturday,
 // it will go to the pervious
 // week...
