+ * The week number and year number of a date may actually be different
+ * then the date itself as specified by the ISO 8601 standard. For
+ * example if Jan 1 year falls on a Friday, the week number will
+ * be the last week number for the previous year (52 of year - 1). Another
+ * example is that the date 2001-12-31 falls on a Monday, its week number
+ * is 1 and its year is 2002. This function provides stripped down
+ * version of the alogrithm described in
+ * http://personal.ecu.edu/mccartyr/ISOwdALG.txt to provide the correct
+ * week number and year number for a given date.
+ *
+ * \param d The date that you want to know the week number for.
+ * \param week A reference to the variable you want to store the week
+ *        number in.
+ * \param year A reference to the variable you want to store the year
+ *        number in.
+ * \param startOnMonday Inform the function whether weeks start on
+ *        Sunday or Monday. Set to true if your weeks start on Monday.
+ * \return false if the supplied date is invalid, true otherwise.
