I added a Highlighter option to your tool!

Check it out! The Tools Enum: `// MARK: - Properties

public enum Tools: Int {
	case finger // Finger tool not implemented
	case pencil
    case highlighter
	case smartPencil
	case eraser
}`

The beginning of touches ended: override public func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) { if self.currentTool == .finger { return } if self.currentTool == .highlighter { opacity = 0.5 } else { opacity = 1.0 } self.printTemplateSource(self.pointsBuffer)
