Get Week - Get the year and the week number of a date 
		
		This action gets a date and returns the year (e.g. 2005)
		and the week number in the year (1-52 or 1-53) to which it belongs.
		
		Weeks are numbered according to the ISO-8601 definitions
		(as presented by Tondering):
		First day of the week is Monday,
		and a week belongs to the year in which most of its days lie.
		E.g. since 2004 started on Wednesday, the 1st week of 2004 was
		29-Dec-2003 through 4-Jan-2004 (3 days in 2003, 4 days in 2004).
		This means 29-Dec-2003 belongs to week 1 of 2004.
		
		 Trigger [required]
		
		The action's template has one non-repetitive trigger: <Date>.
		
		Note that you may also provide as input a "Date and Time" value.
		
		Exits [none required] 
		
		<Week Number> (non-repetitive numeric exit [not required]):
		The week in the year of <Date> (1 through 52 or 1 through 53,
		depending on the year).
		
		<Year> (non-repetitive numeric exit [not required]):
		The year of this week (e.g. 2004).
		
		Notice: Due to the fact that a week may contain days from two different
		years, <Year> is actually "the year to which the week belongs"
		rather than "the year to which the day belongs", so <Year> might be different
		from the year returned by Split Date.
