/**
 * TRANSP
 * Time Transparency
 * RFC 5545 iCalendar 3.8.2.7. page 101
 * 
 * This property defines whether or not an event is transparent to busy time searches.
 * Events that consume actual time SHOULD be recorded as OPAQUE.  Other
 * events, which do not take up time SHOULD be recorded as TRANSPARENT.
 *    
 * Example:
 * TRANSP:TRANSPARENT
 *
 * @author David Bal

 * The property can be specified in following components:
