     * This static class implements a simple logging functionality.
     * Use e.g.
     * ~~~
     * if(Log.Enabled)
     *     Log.Write("bytesRead={0}, MsgLength={1}", bytesRead, state.MsgLength);
     * ~~~
     *
     * Usage:
     * - if(Log.Enabled)  Log.Write(....
     *   For conditional logs. Logs will not appear if logging is not enabled.
     * - Log.Write(....
     *   For Logs that will always appear. E.g. for errors or exceptions.
     * - Log.ConsoleWrite(...
     *   For 'normal' user information. These logs will always be printed also on the console.
     *   This is for future, if I decide to log also into a file. Then the normal Log.Write
     *   would not be visible to the user.
