  wxLogFormatter class is used to format the log messages.
  It implements the default formatting and can be derived from to create custom formatters.
  The default implementation formats the message into a string containing the time stamp, level-dependent prefix and the message itself.
  To change it, you can derive from it and override its Format() method. For example, to include the thread id in the log messages you can use
  And then associate it with wxLog instance using its SetFormatter(). Then, if you call:
  the log output could be something like:
  [7872] d:\testApp\src\testApp.cpp(85) : *** Application started ***
  The default ctor does nothing.
  This function creates the full log message string.
  Override it to customize the output string format.
  This function formats the time stamp part of the log message.
  Override this function if you need to customize just the time stamp.
