/**
 * 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.

 * And then where you configure CocoaLumberjack:
 *
 * purple = DDMakeColor((64/255.0), (0/255.0), (128/255.0));
 *
 * or any UIColor/NSColor constructor.
 *
 * Note: For CLI OS X projects that don't link with AppKit use CLIColor objects instead
 *
 * [[DDTTYLogger sharedInstance] setForegroundColor:purple backgroundColor:nil forTag:PurpleTag];
