-/*
- * Introduction to The Recurrence Generation Functions:
- *
- * Note: This is pretty complicated. See the iCalendar spec (RFC 2445) for
- * the specification of the recurrence rules and lots of examples
- * (sections 4.3.10 & 4.8.5). We also want to support the older
- * vCalendar spec, though this should be easy since it is basically a
- * subset of iCalendar.
- *
- * o An iCalendar event can have any number of recurrence rules specifying
- * occurrences of the event, as well as dates & times of specific
- * occurrences. It can also have any number of recurrence rules and
- * specific dates & times specifying exceptions to the occurrences.
- * So we first merge all the occurrences generated, eliminating any
- * duplicates, then we generate all the exceptions and remove these to
- * form the final set of occurrences.
- *
- * o There are 7 frequencies of occurrences: YEARLY, MONTHLY, WEEKLY, DAILY,
- * HOURLY, MINUTELY & SECONDLY. The 'interval' property specifies the
- * multiples of the frequency which we step by. We generate a 'set' of
- * occurrences for each period defined by the frequency & interval.
- * So for a YEARLY frequency with an interval of 3, we generate a set of
- * occurrences for every 3rd year. We use complete years here - any
- * generated occurrences that occur before the event's start (or after its
- * end) are just discarded.
- *
- * o There are 8 frequency modifiers: BYMONTH, BYWEEKNO, BYYEARDAY, BYMONTHDAY,
- * BYDAY, BYHOUR, BYMINUTE & BYSECOND. These can either add extra occurrences
- * or filter out occurrences. For example 'FREQ=YEARLY;BYMONTH=1,2' produces
- * 2 occurrences for each year rather than the default 1. And
- * 'FREQ=DAILY;BYMONTH=1' filters out all occurrences except those in Jan.
- * If the modifier works on periods which are less than the recurrence
- * frequency, then extra occurrences are added, otherwise occurrences are
- * filtered. So we have 2 functions for each modifier - one to expand events
- * and the other to filter. We use a table of functions for each frequency
- * which points to the appropriate function to use for each modifier.
- *
- * o Any number of frequency modifiers can be used in a recurrence rule.
- * (Though the iCalendar spec says that BYWEEKNO can only be used in a YEARLY
- * rule, and some modifiers aren't appropriate for some frequencies - e.g.
- * BYMONTHDAY is not really useful in a WEEKLY frequency, and BYYEARDAY is
- * not useful in a MONTHLY or WEEKLY frequency).
- * The frequency modifiers are applied in the order given above. The first 5
- * modifier rules (BYMONTH, BYWEEKNO, BYYEARDAY, BYMONTHDAY & BYDAY) all
- * produce the days on which the occurrences take place, and so we have to
- * compute some of these in parallel rather than sequentially, or we may end
- * up with too many days.
- *
- * o Note that some expansion functions may produce days which are invalid,
- * e.g. 31st September, 30th Feb. These invalid days are removed before the
- * BYHOUR, BYMINUTE & BYSECOND modifier functions are applied.
- *
- * o After the set of occurrences for the frequency interval are generated,
- * the BYSETPOS property is used to select which of the occurrences are
- * finally output. If BYSETPOS is not specified then all the occurrences are
- * output.
- *
- *
- * FIXME: I think there are a few errors in this code:
- *
- * 1) I'm not sure it should be generating events in parallel like it says
- * above. That needs to be checked.
- *
- * 2) I didn't think about timezone changes when implementing this. I just
- * assumed all the occurrences of the event would be in local time.
- * But when clocks go back or forwards due to daylight-saving time, some
- * special handling may be needed, especially for the shorter frequencies.
- * e.g. for a MINUTELY frequency it should probably iterate over all the
- * minutes before and after clocks go back (i.e. some may be the same local
- * time but have different UTC offsets). For longer frequencies, if an
- * occurrence lands on the overlapping or non-existant time when clocks
- * go back/forward, then it may need to choose which of the times to use
- * or move the time forward or something. I'm not sure this is clear in the
- * spec.
