+        dtstart = icaltime_from_string("19970101T123000")

+
+3) Iterator over the occurrences
+        struct icaltimetype next;

+
+  How this code works:
+
+  Processing starts when the caller generates a new recurrence
+  iterator via icalrecur_iterator_new(). This routine copies the
+  recurrence rule into the iterator and extracts things like start and
+  end dates. Then, it checks if the rule is legal, using some logic
+  from RFC2445 and some logic that probably should be in RFC2445.
+
+  Then, icalrecur_iterator_new() re-writes some of the BY*
+  arrays. This involves ( via a call to setup_defaults() ) :
+
+  1) For BY rule parts with no data ( ie BYSECOND was not specified )
+  copy the corresponding time part from DTSTART into the BY array. (
+  So impl->by_ptrs[BY_SECOND] will then have one element if is
+  originally had none ) This only happens if the BY* rule part data
+  would expand the number of occurrences in the occurrence set. This
+  lets the code ignore DTSTART later on and still use it to get the
+  time parts that were not specified in any other way.
+  
+  2) For the by rule part that are not the same interval as the
+  frequency -- for HOURLY anything but BYHOUR, for instance -- copy the
+  first data element from the rule part into the first occurrence. For
+  example, for "INTERVAL=MONTHLY and BYHOUR=10,30", initialize the
+  first time to be returned to have an hour of 10.
+
+  Finally, for INTERVAL=YEARLY, the routine expands the rule to get
+  all of the days specified in the rule. The code will do this for
+  each new year, and this is the first expansion. This is a special
+  case for the yearly interval; no other frequency gets expanded this
+  way. The yearly interval is the most complex, so some special
+  processing is required.
+
+  After creating a new iterator, the caller will make successive calls
+  to icalrecur_iterator_next() to get the next time specified by the
+  rule. The main part of this routine is a switch on the frequency of
+  the rule. Each different frequency is handled by a different
+  routine. 
+
+  For example, next_hour handles the case of INTERVAL=HOURLY, and it
+  is called by other routines to get the next hour. First, the routine
+  tries to get the next minute part of a time with a call to
+  next_minute(). If next_minute() returns 1, it has reached the end of
+  its data, usually the last element of the BYMINUTE array. Then, if
+  there is data in the BYHOUR array, the routine changes the hour to
+  the next one in the array. If INTERVAL=HOURLY, the routine advances
+  the hour by the interval.
+
+  If the routine used the last hour in the BYHOUR array, and the
+  INTERVAL=HOURLY, then the routine calls increment_monthday() to set
+  the next month day. The increment_* routines may call higher routine
+  to increment the month or year also.
+
+  The code for INTERVAL=DAILY is handled by next_day(). First, the
+  routine tries to get the next hour part of a time with a call to
+  next_hour. If next_hour() returns 1, it has reached the end of its
+  data, usually the last element of the BYHOUR array. This means that
+  next_day() should increment the time to the next day. If FREQUENCY==DAILY,
+  the routine increments the day by the interval; otherwise, it
+  increments the day by 1.
+
+  Next_day() differs from next_hour because it does not use the BYDAY
+  array to select an appropriate day. Instead, it returns every day (
+  incrementing by 1 if the frequency is not DAILY with INTERVAL!=1)
+  Any days that are not specified in an non-empty BYDAY array are
+  filtered out later.
+
+  Generally, the flow of these routine is for a next_* call a next_*
+  routine of a lower interval ( next_day calls next_hour) and then to
+  possibly call an increment_* routine of an equal or higher
+  interval. ( next_day calls increment_monthday() )
+
+  When the call to the original next_* routine returns,
+  icalrecur_iterator_next() will check the returned data against other
+  BYrule parts to determine if is should be excluded by calling
+  check_contracting_rules. Generally, a contracting rule is any with a
+  larger time span than the interval. For instance, if
+  INTERVAL=DAILY, BYMONTH is a contracting rule part. 
+
+  Check_contracting_rules() uses icalrecur_check_rulepart() to do its
+  work. icalrecur_check_rulepart() uses expand_map[] to determine if a rule
+  is contracting, and if it is, and if the BY rule part has some data,
+  then the routine checks if the value of a component of the time is
+  part of the byrule part. For instance, for "INTERVAL=DAILY;
+  BYMONTH=6,10", icalrecur_check_rulepart() would check that the time value
+  given to it has a month of either 6 or 10.
+
+  Finally, icalrecur_iterator_next() does a few other checks on the
+  time value, and if it passes, it returns the time.
+
+  A note about the end_of_data flag. The flag indicates that the
+  routine is at the end of its data -- the last BY rule if the routine
+  is using by rules, or the last day of the week/month/year/etc if
+  not.
+
+  This flag is usually set early in a next_* routine and returned in
+  the end. The way it is used allows the next_* routine to set the
+  last time back to the first element in a BYxx rule, and then signal
+  to the higer level routine to increment the next higher level. For
+  instance. WITH FREQ=MONTHLY;BYDAY=TU,FR, After next_weekday_by_month
+  runs though both TU and FR, it sets the week day back to TU and sets
+  end_of_data to 1x. This signals next_month to increment the month.

+        dtstart = icaltime_from_string("19970101T123000")

+
+3) Iterator over the occurrences
+        struct icaltimetype next;

+               && !icaltime_is_null_time(next){
