Description

`month_weekday_iterator` public member functions

month_weekday_iterator(date_type d, int f,

`f`	Factor, i.e. how many month to forward on each iteration.
`originWeekNo`	The week number of a month [1..5] to set up the iterator.
`originWeekday`	The day of week [0..6] to set up the iterator.
