3D/2D Maze Generator (Blender/Python Script) for 3D Printers and Laser Cutters

**EDIT 1 (3/24/15): Added dual extrusion support.**

**EDIT 2 (3/24/2015): Added option to have entrance and exits closed, also added setting to make 2D vector path instead of 3D mesh. Fixed minor redundancy in code.**

**EDIT 3 (3/25/15): Fixed minor settings conflict, added more comments for clarity.**

So I've had a thing for maze generation for a while. While I wrote a few different games in HTML 5/Javascript and C, I wanted to make something that was actually physically real.

Besides, I like the looks of the classic recursive-backtracker algorithm more than any other, and it's so deliciously simple to implement. Also, I really, really like generating mazes. :) So, I decided to write my own.

Initially, I wanted to implement it in OpenSCAD, but because it uses a functional language
