Maze masking

The source code requires [OpenSCAD](http://openscad.org) and [dotSCAD](https://github.com/JustinSDK/dotSCAD). It can be found on [dotSCAD/examples/maze/maze_masking.scad](https://github.com/JustinSDK/dotSCAD/blob/master/examples/maze/maze_masking.scad).

Given a list of 0s and 1s that represent a black-and-white image. 0 is for black and 1 is for white. The code can fit a maze to the white shape.

I provide a tool [img2binary](https://github.com/JustinSDK/img2binary) for converting an image into 0 and 1.
