// Details:	MI common code MI Out-of-band (Async) Record class. A class that encapsulates 
//			MI result record data and the forming/format of data added to it.
//			Out-of-band records are used to notify the GDB/MI client of additional 
//			changes that have occurred. Those changes can either be a consequence 
//			of GDB/MI (e.g., a breakpoint modified) or a result of target activity 
//			(e.g., target stopped). 
//			The syntax is as follows:
//			"*" type ( "," result )*
//			type ==> running | stopped
//
//			The Out-of-band record can be retrieve at any time *this object is
//			instantiated so unless work is done on *this Out-of-band record then it is
//			possible to return a malformed Out-of-band record. If nothing has been set 
//			or added to *this MI Out-of-band record object then text "<Invalid>" will 
//			be returned.
//
//			More information see: 
//			http://ftp.gnu.org/old-gnu/Manuals/gdb-5.1.1/html_chapter/gdb_22.html//
