*
* Once initialized this class can also be serialized saved and continue
* iteration from the last point.
*
* NOTE: it is intended that this class is to be used
* with ICAL.Event which handles recurrence exceptions.
*
* @example
* // assuming event is a parsed ical component
* var event;
*
* var expand = new ICAL.RecurExpansion({
* component: event,
* dtstart: event.getFirstPropertyValue('dtstart')
* });
*
* // remember there are infinite rules
* // so its a good idea to limit the scope
* // of the iterations then resume later on.
*
* // next is always an ICAL.Time or null
* var next;
*
* while (someCondition && (next = expand.next())) {
* // do something with next
* }
*
* // save instance for later
* var json = JSON.stringify(expand);
*
* //...
*
* // NOTE: if the component's properties have
* // changed you will need to rebuild the
* // class and start over. This only works
* // when the component's recurrence info is the same.
* var expand = new ICAL.RecurExpansion(JSON.parse(json));
