My new painter for BlackHole. It much like David's DrawingBot but feature more shapes and style. Note that this painter is untested now, if you see any exception, please let me know here.

You can either make it a class within your robot or extend this class (of course, edit this class to extends AdvancedRobot).

This code is a bit messy because it spent 2 hours wrote constructor for those shape classes and forget that they are private!
