Generate a date for a given teaching week in a teaching period, in the specified format. Return the date of the Monday of the week, plus an optional signed offset.
@period: The teaching period for which to generate the date. [required]
@week: The number of the week in the specified teaching period. [required]
@format: How to format the date.
'day+long-name' => [FNn] [D] [MNn] (e.g., Friday 10 August)
'day+short-name' => [FNn,*-3] [D] [MNn] (e.g., Fri 10 August)
'day' => [D] [MNn] (e.g., 10 August)
'day-short' => [D] [MNn,*-3] (e.g., 10 Aug)
'day+year' => [D] [MNn], [Y] (e.g., 10 August, 2013)
'day-short+year' => [D] [MNn,*-3], [Y] (e.g., 10 Aug, 2013)
'ISO' => [Y0001]-[M01]-[D01] (e.g., 2012-08-10)
date picture string => Any valid XSLT date picture specification (see http://www.w3.org/TR/xslt20/#date-picture-string).
@offset: A signed offset specified as an XSLT duration, e.g., "P1D" for plus one day, "-P4D" for minus four days.
