/**
  *This class provides a logger for Terminal output or Xcode console output,
  *depending on where you are running your code.
 *
  *As described in the "Getting Started" page,
  *the traditional NSLog() function directs it's output to two places:
 *
  *- Apple System Log (so it shows up in Console.app)
  *- StdErr (if stderr is a TTY, so log statements show up in Xcode console)
 *
  *To duplicate NSLog() functionality you can simply add this logger and an asl logger.
  *However, if you instead choose to use file logging (for faster performance),
  *you may choose to use only a file logger and a tty logger.
