initialization

// The TLoggerProFileAppender has its defaults defined as follows:
//   DEFAULT_MAX_BACKUP_FILE_COUNT = 5;
//   DEFAULT_MAX_FILE_SIZE_KB = 1000;
//
//  You can override these dafaults passing parameters to the constructor.
//  Here's some configuration examples:
//
//  Creates log with default settings
//  _Log := BuildLogWriter([TLoggerProFileAppender.Create]);
//
//  Create logs in the exe' same folder. Backupset = 10, max size for single file 5k
//  _Log := BuildLogWriter([TLoggerProFileAppender.Create(10, 5)]);
//
//  Creates log in the AppData/Roaming with PID in the filename
//  _Log := BuildLogWriter([TLoggerProFileAppender.Create(10, 5,
//     TPath.GetHomePath,
//     TLoggerProFileAppender.DEFAULT_FILENAME_FORMAT_WITH_PID
//   )]);
//
//  Creates log in the same folder with PID in the filename
//  _Log := BuildLogWriter([TLoggerProFileAppender.Create(
//      10,
//      5,
//      '',
//      TLoggerProFileAppender.DEFAULT_FILENAME_FORMAT_WITH_PID,
//      GetDefaultLogRenderer
//      )]);
//
//  Creates logs in the ..\..\ folder using the default filename
//  The FilteringFileAppender selects the 'TAG1' and 'TAG2' log messages into a separate file
   _Log := BuildLogWriter([
     TLoggerProFileAppender.Create(10, 5, '..\..',
       TLoggerProFileAppender.DEFAULT_FILENAME_FORMAT,
       TLogItemRendererNoTag.Create),
     TLoggerProFilter.Build(
       TLoggerProSimpleFileAppender.Create(10, 5, '..\..'),
       function(ALogItem: TLogItem): boolean
       begin
         Result := (ALogItem.LogTag = 'TAG1') or (ALogItem.LogTag = 'TAG2');
