    Class: COutput

    Method: NewL

    Description: Two-phased constructor.

    NOTE: At the moment there is only one output module implemented

    Parameters: const TDesC& aTestPath: in: Path to logged information

                const TDesC& aTestFile: in: Log name for information

                TLoggerType aLoggerType: in: Log file type

                TOutput aOutput: in: Output source

                TBool aOverWrite: in: Indicator to file overwrite

                TBool aWithTimeStamp: in: Indicator to time stamp

                TBool aWithLineBreak: in: Indicator to line break

                TBool aWithEventRanking: in: Indicator to event ranking

                TBool aThreadIdToLogFile: in: Indicator to thread id adding to

                                              end of the log file

                TBool aCreateLogDir: in: Indicator to directory creation

                TInt  aStaticBufferSize

                TBool aUnicode: in: Indicator if file has to be in unicode format

    Return Values: COutput*: pointer to COutput object

    Errors/Exceptions:  Leaves if called CFileOutput::NewL method fails
