+* Description:
+* FTP server answer parser
+* Author:	Philippe Gabriel
+* RFC 959 defines the syntax for answers sent back by FTP servers
+* TFTPServerAnswerParser parses these answers 
+* RFC says answers are:
+* 1) single line answer
+* xxx<space><alphadecimal chars><0x0d><0x0a>
+* 2) multiline answer
+* xxx-<alphadecimal chars><0x0d><0x0a>
+* <several lines>
+* <0x0d><0x0a>xxx<space><alphadecimal chars><0x0d><0x0a>
+* We parse these regular expressions with the class TFTPServerAnswerParser
+* implementing an FSM to parse a regular expression
+* The parser is called with the method:
+* Parse(const TDesC& aBuffer)
+* parameter: aBuffer contains an answer to be parsed
+* returns:
+* 1) True
+* a server answer is available 
+* Get the answer with: ServerAnswer(TDes& aServerAnswer)
+* Get the number of chars from the buffer corresponding to the
+* parsed answer with NChars()
+* the NChars first chars can be flushed from the buffer
+* note: in this case, call the parser again before
+* we do any more socket receive operation, to parse the rest of the buffer
+* 2)False
+* no answer is available yet
+* buffer can be completely flushed
+*
