Usage:
autoScrollLabel.text = @"This text may be clipped, but now it will be scrolled.";
autoScrollLabel.textColor = [UIColor blueColor];
autoScrollLabel.labelSpacing = 35; // distance between start and end labels
autoScrollLabel.pauseInterval = 3.7; // seconds of pause before scrolling starts again
autoScrollLabel.scrollSpeed = 30; // pixels per second
autoScrollLabel.textAlignment = UITextAlignmentCenter; // centers text when no auto-scrolling is applied
