/**
* Recurrence Id Property
* @package qCal
* @copyright Luke Visinoni (luke.visinoni@gmail.com)
* @author Luke Visinoni (luke.visinoni@gmail.com)
* @license GNU Lesser General Public License
* @todo This has some pretty specific rules as to how it is to be used.
* Make sure that all of them are considered.
*
* RFC 2445 Definition
*
* Property Name: RECURRENCE-ID
*
* Purpose: This property is used in conjunction with the "UID" and
* "SEQUENCE" property to identify a specific instance of a recurring
* "VEVENT", "VTODO" or "VJOURNAL" calendar component. The property
* value is the effective value of the "DTSTART" property of the
* recurrence instance.
*
* Value Type: The default value type for this property is DATE-TIME.
* The time format can be any of the valid forms defined for a DATE-TIME
* value type. See DATE-TIME value type definition for specific
* interpretations of the various forms. The value type can be set to
* DATE.
*
* Property Parameters: Non-standard property, value data type, time
* zone identifier and recurrence identifier range parameters can be
* specified on this property.
*
* Conformance: This property can be specified in an iCalendar object
* containing a recurring calendar component.
*
* Description: The full range of calendar components specified by a
* recurrence set is referenced by referring to just the "UID" property
* value corresponding to the calendar component. The "RECURRENCE-ID"
* property allows the reference to an individual instance within the
* recurrence set.
*
* If the value of the "DTSTART" property is a DATE type value, then the
* value MUST be the calendar date for the recurrence instance.
*
* The date/time value is set to the time when the original recurrence
* instance would occur; meaning that if the intent is to change a
* Friday meeting to Thursday, the date/time is still set to the
* original Friday meeting.
*
* The "RECURRENCE-ID" property is used in conjunction with the "UID"
* and "SEQUENCE" property to identify a particular instance of a
* recurring event, to-do or journal. For a given pair of "UID" and
* "SEQUENCE" property values, the "RECURRENCE-ID" value for a
* recurrence instance is fixed. When the definition of the recurrence
* set for a calendar component changes, and hence the "SEQUENCE"
* property value changes, the "RECURRENCE-ID" for a given recurrence
* instance might also change.The "RANGE" parameter is used to specify
* the effective range of recurrence instances from the instance
* specified by the "RECURRENCE-ID" property value. The default value
* for the range parameter is the single recurrence instance only. The
* value can also be "THISANDPRIOR" to indicate a range defined by the
* given recurrence instance and all prior instances or the value can be
* "THISANDFUTURE" to indicate a range defined by the given recurrence
* instance and all subsequent instances.
*
* Format Definition: The property is defined by the following notation:
*
* recurid = "RECURRENCE-ID" ridparam ":" ridval CRLF
*
* ridparam = *(
*
* ; the following are optional,
* ; but MUST NOT occur more than once
*
* (";" "VALUE" "=" ("DATE-TIME" / "DATE)) /
* (";" tzidparam) / (";" rangeparam) /
* ; the following is optional,
* ; and MAY occur more than once
*
* (";" xparam)
*
* )
*
* ridval = date-time / date
* ;Value MUST match value type
*
* Example: The following are examples of this property:
*
* RECURRENCE-ID;VALUE=DATE:19960401
*
* RECURRENCE-ID;RANGE=THISANDFUTURE:19960120T120000Z
