/**
 * FREEBUSY
 * Free/Busy Time
 * RFC 5545, 3.8.2.6, page 100
 * 
 * This property defines one or more free or busy time intervals.
 * 
 * These time periods can be specified as either a start
 * and end DATE-TIME or a start DATE-TIME and DURATION.  The date and
 * time MUST be a UTC time format.  Internally, the values are stored only as 
 * start DATE-TIME and DURATION.  Any values entered as start and end as both
 * DATE-TIME are converted to the start DATE-TIME and DURATION.
 * 
 * Examples:
 * FREEBUSY;FBTYPE=BUSY-UNAVAILABLE:19970308T160000Z/PT8H30M
 * FREEBUSY;FBTYPE=FREE:19970308T160000Z/PT3H,19970308T200000Z/PT1H
 *  ,19970308T230000Z/19970309T000000Z
 * 
 * Note: The above example is converted and outputed as the following:
 * FREEBUSY;FBTYPE=FREE:19970308T160000Z/PT3H,19970308T200000Z/PT1H
 *  ,19970308T230000Z/PT1H

 * The property can be specified in following components:
