DLOG

// taken from http://iphoneincubator.com/blog/tag/nslog

#ifdef DEBUG
# define DLOG(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);
#else
# define DLOG(...)
#endif

// ALog always displays output regardless of the DEBUG setting
#define ALOG(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);

// ELOG - errors
#define ELOG(err, fmt, ...) NSLog((@"ERROR: (%@) %s [Line %d] " fmt), err, __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);
