Parametric Burr Puzzle Module

This OpenScad module allows you to generate models for arbitrary Burr puzzle pieces.

The bit pattern used for configuration is identical with the one on the following site: http://www.research.ibm.com/BurrPuzzles/index.html

You can use the Burr calculator on this site to calculate and print your own puzzles.

Additionally, the file contains the burrx() module which allows the corner blocks on the lower level to be set. It basically extends the pattern to 4*L bits.
