-/*
- * 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.
